SLASED9A – NOVEMBER 2016 – REVISED NOVEMBER 2017
MUX36xxx 36-V, Low-Capacitance, Low-Leakage-Current, Precision Analog Multiplexers
1 Features
3 Description
•
The MUX36S16 and MUX36D08 (MUX36xxx) are
modern complementary metal-oxide semiconductor
(CMOS) precision analog multiplexers (muxes). The
MUX36S16 offers 16:1 single-ended channels,
whereas the MUX36D08 offers differential 8:1 or dual
8:1 single-ended channels. The MUX36S16 and
MUX36D08 work equally well with either dual
supplies (±5 V to ±18 V) or a single supply (10 V to
36 V). These devices also perform well with
symmetric supplies (such as VDD = 12 V, VSS = –12
V), and unsymmetric supplies (such as VDD = 12 V,
VSS = –5 V). All digital inputs have transistortransistor logic (TTL) compatible thresholds, providing
both TTL and CMOS logic compatibility when
operating in the valid supply voltage range.

7.2 On-Resistance
The on-resistance of the MUX36xxx is the ohmic resistance across the source (Sx, SxA, or SxB) and drain (D,
DA, or DB) pins of the device. The on-resistance varies with input voltage and supply voltage. The symbol RON is
used to denote on-resistance. The measurement setup used to measure RON is shown in Figure 26. Voltage (V)
and current (ICH) are measured using this setup, and RON is computed as shown in Equation 1:
RON = V / ICH

7.3 Off Leakage
There are two types of leakage currents associated with a switch during the OFF state:
1. Source off-leakage current
2. Drain off-leakage current
Source leakage current is defined as the leakage current flowing into or out of the source pin when the switch is
off. This current is denoted by the symbol IS(OFF).
Drain leakage current is defined as the leakage current flowing into or out of the drain pin when the switch is off.
This current is denoted by the symbol ID(OFF).
The setup used to measure both off-leakage currents is shown in Figure 27

Break-before-make delay is a safety feature that prevents two inputs from connecting when the MUX36xxx is
switching. The MUX36xxx output first breaks from the ON-state switch before making the connection with the
next ON-state switch. The time delay between the break and the make is known as break-before-make delay.

7.9 Charge Injection
The MUX36xxx have a simple transmission-gate topology. Any mismatch in capacitance between the NMOS and
PMOS transistors results in a charge injected into the drain or source during the falling or rising edge of the gate
signal. The amount of charge injected into the source or drain of the device is known as charge injection, and is
denoted by the symbol QINJ. Figure 33 shows the setup used to measure charge injection.

The total harmonic distortion (THD) of a signal is a measurement of the harmonic distortion, and is defined as the
ratio of the sum of the powers of all harmonic components to the power of the fundamental frequency at the mux
output. The on-resistance of the MUX36xxx varies with the amplitude of the input signal and results in distortion
when the drain pin is connected to a low-impedance load. Total harmonic distortion plus noise is denoted as
THD+N. Figure 37 shows the setup used to measure THD+N of the MUX36xxx.

8.3 Feature Description
8.3.1 Ultralow Leakage Current
The MUX36xxx provide extremely low on- and off-leakage currents. The MUX36xxx are capable of switching
signals from high source-impedance inputs into a high input-impedance op amp with minimal offset error
because of the ultra-low leakage currents. Figure 38 shows typical leakage currents of the MUX36xxx versus
temperature.

8.3.3 Bidirectional Operation
The MUX36xxx are operable as both a mux and demux. The source (Sx, SxA, SxB) and drain (D, DA, DB) pins
of the MUX36xxx are used either as input or output. Each MUX36xxx channel has very similar characteristics in
both directions.
8.3.4 Rail-to-Rail Operation
The valid analog signal for the MUX36xxx ranges from VSS to VDD. The input signal to the MUX36xxx swings
from VSS to VDD without any significant degradation in performance. The on-resistance of the MUX36xxx varies
with input signal, as shown in Figure 42

9 Application and Implementation
NOTE
Information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. TI’s customers are
responsible for determining suitability of components for their purposes. Customers should
validate and test their design implementation to confirm system functionality.
9.1 Application Information
The MUX36xxx family offers outstanding input/output leakage currents and ultra-low charge injection. These
devices operate up to 36 V, and offer true rail-to-rail input and output. The on-capacitance of the MUX36xxx is
very low. These features makes the MUX36xxx a family of precision, robust, high-performance analog
multiplexer for high-voltage, industrial applications.
9.2 Typical Application
Figure 43 shows a 16-bit, differential, 8-channel, multiplexed, data-acquisition system. This example is typical in
industrial applications that require low distortion and a high-voltage differential input. The circuit uses the
ADS8864, a 16-bit, 400-kSPS successive-approximation-resistor (SAR) analog-to-digital converter (ADC), along
with a precision, high-voltage, signal-conditioning front end, and a 4-channel differential mux. This TI Precision
Design details the process for optimizing the precision, high-voltage, front-end drive circuit using the MUX36D08,
OPA192 and OPA140 to achieve excellent dynamic performance and linearity with the ADS8864.

input. The design requirements for this block design are:
• System supply voltage: ±15 V
• ADC supply voltage: 3.3 V
• ADC sampling rate: 400 kSPS
• ADC reference voltage (REFP): 4.096 V
• System input signal: A high-voltage differential input signal with a peak amplitude of 20 V and frequency
(fIN) of 10 kHz are applied to each differential input of the mux.

9.2.2 Detailed Design Procedure
The purpose of this precision design is to design an optimal, high-voltage, multiplexed, data-acquisition system
for highest system linearity and fast settling. The overall system block diagram is illustrated in Figure 43. The
circuit is a multichannel, data-acquisition signal chain consisting of an input low-pass filter, mux, mux output
buffer, attenuating SAR ADC driver, and the reference driver. The architecture allows fast sampling of multiple
channels using a single ADC, providing a low-cost solution. This design systematically approaches each analog
circuit block to achieve a 16-bit settling for a full-scale input stage voltage and linearity for a 10-kHz sinusoidal
input signal at each input channel. Detailed design considerations and component selection procedure can be
found in the TI Precision Design TIPD151, 16-Bit, 400-kSPS, 4-Channel Multiplexed Data-Acquisition System for
High-Voltage Inputs with Lowest Distortion.

10 Power Supply Recommendations
The MUX36xxx operates across a wide supply range of ±5 V to ±18 V (10 V to 36 V in single-supply mode). The
devices also perform well with unsymmetric supplies such as VDD = 12 V and VSS= –5 V. For reliable operation,
use a supply decoupling capacitor ranging between 0.1 µF to 10 µF at both the VDD and VSS pins to ground.
The on-resistance of the MUX36xxx varies with supply voltage, as illustrated in Figure 45

11 Layout
11.1 Layout Guidelines
Figure 46 illustrates an example of a PCB layout with the MUX36S16IPW, and Figure 47 illustrates an example
of a PCB layout with MUX36D08IPW.
Some key considerations are:
1. Decouple the VDD and VSS pins with a 0.1-µF capacitor, placed as close to the pin as possible. Make sure
that the capacitor voltage rating is sufficient for the VDD and VSS supplies.
2. Keep the input lines as short as possible. In case of the differential signal, make sure the A inputs and B
inputs are as symmetric as possible.
3. Use a solid ground plane to help distribute heat and reduce electromagnetic interference (EMI) noise pickup.
4. Do not run sensitive analog traces in parallel with digital traces. Avoid crossing digital and analog traces if
possible, and only make perpendicular crossings when necessary.

IMPORTANT NOTICE
Texas Instruments Incorporated (TI) reserves the right to make corrections, enhancements, improvements and other changes to its
semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest issue. Buyers
should obtain the latest relevant information before placing orders and should verify that such information is current and complete.
TI’s published terms of sale for semiconductor products (http://www.ti.com/sc/docs/stdterms.htm) apply to the sale of packaged integrated
circuit products that TI has qualified and released to market. Additional terms may apply to the use or sale of other types of TI products and
services.
Reproduction of significant portions of TI information in TI data sheets is permissible only if reproduction is without alteration and is
accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such reproduced
documentation. Information of third parties may be subject to additional restrictions. Resale of TI products or services with statements
different from or beyond the parameters stated by TI for that product or service voids all express and any implied warranties for the
associated TI product or service and is an unfair and deceptive business practice. TI is not responsible or liable for any such statements.
Buyers and others who are developing systems that incorporate TI products (collectively, “Designers”) understand and agree that Designers
remain responsible for using their independent analysis, evaluation and judgment in designing their applications and that Designers have
full and exclusive responsibility to assure the safety of Designers' applications and compliance of their applications (and of all TI products
used in or for Designers’ applications) with all applicable regulations, laws and other applicable requirements. Designer represents that, with
respect to their applications, Designer has all the necessary expertise to create and implement safeguards that (1) anticipate dangerous
consequences of failures, (2) monitor failures and their consequences, and (3) lessen the likelihood of failures that might cause harm and
take appropriate actions. Designer agrees that prior to using or distributing any applications that include TI products, Designer will
thoroughly test such applications and the functionality of such TI products as used in such applications.
TI’s provision of technical, application or other design advice, quality characterization, reliability data or other services or information,
including, but not limited to, reference designs and materials relating to evaluation modules, (collectively, “TI Resources”) are intended to
assist designers who are developing applications that incorporate TI products; by downloading, accessing or using TI Resources in any
way, Designer (individually or, if Designer is acting on behalf of a company, Designer’s company) agrees to use any particular TI Resource
solely for this purpose and subject to the terms of this Notice.
TI’s provision of TI Resources does not expand or otherwise alter TI’s applicable published warranties or warranty disclaimers for TI
products, and no additional obligations or liabilities arise from TI providing such TI Resources. TI reserves the right to make corrections,
enhancements, improvements and other changes to its TI Resources. TI has not conducted any testing other than that specifically
described in the published documentation for a particular TI Resource.
Designer is authorized to use, copy and modify any individual TI Resource only in connection with the development of applications that
include the TI product(s) identified in such TI Resource. NO OTHER LICENSE, EXPRESS OR IMPLIED, BY ESTOPPEL OR OTHERWISE
TO ANY OTHER TI INTELLECTUAL PROPERTY RIGHT, AND NO LICENSE TO ANY TECHNOLOGY OR INTELLECTUAL PROPERTY
RIGHT OF TI OR ANY THIRD PARTY IS GRANTED HEREIN, including but not limited to any patent right, copyright, mask work right, or
other intellectual property right relating to any combination, machine, or process in which TI products or services are used. Information
regarding or referencing third-party products or services does not constitute a license to use such products or services, or a warranty or
endorsement thereof. Use of TI Resources may require a license from a third party under the patents or other intellectual property of the
third party, or a license from TI under the patents or other intellectual property of TI.
TI RESOURCES ARE PROVIDED “AS IS” AND WITH ALL FAULTS. TI DISCLAIMS ALL OTHER WARRANTIES OR
REPRESENTATIONS, EXPRESS OR IMPLIED, REGARDING RESOURCES OR USE THEREOF, INCLUDING BUT NOT LIMITED TO
ACCURACY OR COMPLETENESS, TITLE, ANY EPIDEMIC FAILURE WARRANTY AND ANY IMPLIED WARRANTIES OF
MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT OF ANY THIRD PARTY INTELLECTUAL
PROPERTY RIGHTS. TI SHALL NOT BE LIABLE FOR AND SHALL NOT DEFEND OR INDEMNIFY DESIGNER AGAINST ANY CLAIM,
INCLUDING BUT NOT LIMITED TO ANY INFRINGEMENT CLAIM THAT RELATES TO OR IS BASED ON ANY COMBINATION OF
PRODUCTS EVEN IF DESCRIBED IN TI RESOURCES OR OTHERWISE. IN NO EVENT SHALL TI BE LIABLE FOR ANY ACTUAL,
DIRECT, SPECIAL, COLLATERAL, INDIRECT, PUNITIVE, INCIDENTAL, CONSEQUENTIAL OR EXEMPLARY DAMAGES IN
CONNECTION WITH OR ARISING OUT OF TI RESOURCES OR USE THEREOF, AND REGARDLESS OF WHETHER TI HAS BEEN
ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
Unless TI has explicitly designated an individual product as meeting the requirements of a particular industry standard (e.g., ISO/TS 16949
and ISO 26262), TI is not responsible for any failure to meet such industry standard requirements.
Where TI specifically promotes products as facilitating functional safety or as compliant with industry functional safety standards, such
products are intended to help enable customers to design and create their own applications that meet applicable functional safety standards
and requirements. Using products in an application does not by itself establish any safety features in the application. Designers must
ensure compliance with safety-related requirements and standards applicable to their applications. Designer may not use any TI products in
life-critical medical equipment unless authorized officers of the parties have executed a special contract specifically governing such use.
Life-critical medical equipment is medical equipment where failure of such equipment would cause serious bodily injury or death (e.g., life
support, pacemakers, defibrillators, heart pumps, neurostimulators, and implantables). Such equipment includes, without limitation, all
medical devices identified by the U.S. Food and Drug Administration as Class III devices and equivalent classifications outside the U.S.
TI may expressly designate certain products as completing a particular qualification (e.g., Q100, Military Grade, or Enhanced Product).
Designers agree that it has the necessary expertise to select the product with the appropriate qualification designation for their applications
and that proper product selection is at Designers’ own risk. Designers are solely responsible for compliance with all legal and regulatory
requirements in connection with such selection.
Designer will fully indemnify TI and its representatives against any damages, costs, losses, and/or liabilities arising out of Designer’s noncompliance with the terms and provisions of this Notice.
