MP C50 MPC508A MPC509A 8 MP C50 9 SBFS019A – JANUARY 1988 — REVISED OCTOBER 2003 Single-Ended 8-Channel/Differential 4-Channel CMOS ANALOG MULTIPLEXERS FEATURES FUNCTIONAL DIAGRAMS ● ANALOG OVERVOLTAGE PROTECTION: 70VPP ● NO CHANNEL INTERACTION DURING OVERVOLTAGE ● BREAK-BEFORE-MAKE SWITCHING ● ANALOG SIGNAL RANGE: ±15V ● STANDBY POWER: 7.5mW typ ● TRUE SECOND SOURCE 1kΩ In 1 Out 1kΩ In 2 Decoder/ Driver 1kΩ In 8 Overvoltage Clamp and Signal Isolation DESCRIPTION The MPC508A is an 8-channel single-ended analog multiplexer and the MPC509A is a 4-channel differential multiplexer. The MPC508A and MPC509A multiplexers have input overvoltage protection. Analog input voltages may exceed either power supply voltage without damaging the device or disturbing the signal path of other channels. The protection circuitry assures that signal fidelity is maintained even under fault conditions that would destroy other multiplexers. Analog inputs can withstand 70VPP signal levels and standard ESD tests. Signal sources are protected from short circuits should multiplexer power loss occur; each input presents a 1kΩ resistance under this condition. Digital inputs can also sustain continuous faults up to 4V greater than either supply voltage. 5V Ref Level Shift (1) (1) NOTE: (1) Digital Input Protection.

Single-Ended Multiplexer Static Accuracy The major contributors to static transfer accuracy for singleended multiplexers are: Source resistance loading error; Multiplexer ON resistance error; and, dc offset error caused by both load bias current and multiplexer leakage current. Static accuracy errors in a differential multiplexer are difficult to control, especially when it is used for multiplexing low-level signals with full-scale ranges of 10mV to 100mV. The matching properties of the multiplexer, source and output load play a very important part in determining the transfer accuracy of the multiplexer. The source impedance unbalance, common-mode impedance, load bias current mismatch, load differential impedance mismatch, and commonmode impedance of the load all contribute errors to the multiplexer. The multiplexer ON resistance mismatch, leakage current mismatch and ON resistance also contribute to differential errors. The effects of these errors can be minimized by following the general guidelines described in this section, especially for low-level multiplexing applications. Refer to Figure 2. Resistive Loading Errors Load (Output Device) Characteristics The source and load impedances will determine the input resistive loading errors. To minimize these errors: • Use devices with very low bias current. Generally, FET input amplifiers should be used for low-level signals less than 50mV FSR. Low bias current bipolar input amplifiers are acceptable for signal ranges higher than 50mV FSR. Bias current matching will determine the input offset. • The system dc common-mode rejection (CMR) can never be better than the combined CMR of the multiplexer and driven load. System CMR will be less than the device which has the lower CMR figure. • Load impedances, differential and common-mode, should be 1010Ω or higher. • • Keep loading impedance as high as possible. This minimizes the resistive loading effects of the source resistance and multiplexer ON resistance. As a guideline, load impedances of 108Ω, or greater, will keep resistive loading errors to 0.002% or less for 1000Ω source impedances. A 106Ω load impedance will increase source loading error to 0.2% or more. Use sources with impedances as low as possible. 1000Ω source resistance will present less than 0.001% loading error and 10kΩ source resistance will increase source loading error to 0.01% with a 108 load impedance. VM Source and Multiplexer Resistive Loading Error ∈(RS + RON ) = IBIAS RON RS1 Input resistive loading errors are determined by the following relationship (see Figure 1). RS + RON × 100% RS + RON + RL ROFF RS8 VS1 Measured Voltage IL ZL VS8 where RS = source resistance RL = load resistance RON = multiplexer ON resistance FIGURE 1. MPC508A DC Accuracy Equivalent Circuit. RS1 Input Offset Voltage RON1A IBIAS A Cd/2 Bias current generates an input OFFSET voltage as a result of the IR drop across the multiplexer ON resistance and source resistance. A load bias current of 10nA will generate an offset voltage of 20µV if a 1kΩ source is used. In general, for the MPC508A, the OFFSET voltage at the output is determined by: Rd/2 IL VS1 RCM1 RCM RS1B RON1B IBIAS B ZL CCM Cd/2 Rd/2 RS4A ROFF4A VOFFSET = (IB + IL) (RON + RS) ILB where IB = Bias current of device multiplexer is driving IL = Multiplexer leakage current RON = Multiplexer ON resistance RS = source resistance VS8 RS48 ROFF4B RCM4 FIGURE 2. MPC509A DC Accuracy Equivalent Circuit. MPC508A, MPC509A SBFS019A www.ti.com 5 Source Characteristics • • • The source impedance unbalance will produce offset, common-mode and channel-to-channel gain-scatter errors. Use sources which do not have large impedance unbalances if at all possible. RSA Node A CSA RCMS Source CSB Keep source impedances as low as possible to minimize resistive loading errors. CCMS Minimize ground loops. If signal lines are shielded, ground all shields to a common point at the system analog common. RSB CdA RdA ZCM MPC509A Load Channel RdB Node B CdB If the MPC509A is used for multiplexing high-level signals of ±1V to ±10V full-scale ranges, the foregoing precautions should still be taken, but the parameters are not as critical as for low-level signal applications. DYNAMIC CHARACTERISTICS Settling Time The gate-to-source and gate-to-drain capacitance of the CMOS FET switches, the RC time constants of the source and the load determine the settling time of the multiplexer. Governed by the charge transfer relation i = C (dV/dt), the charge currents transferred to both load and source by the analog switches are determined by the amplitude and rise time of the signal driving the CMOS FET switches and the gate-to-drain and gate-to-source junction capacitances as shown in Figures 3 and 4. Using this relationship, one can see that the amplitude of the switching transients, seen at the source and load, decrease proportionally as the capacitance of the load and source increase. The trade-off for reduced switching transient amplitude is increased settling time. In effect, the amplitude of the transients seen at the source and load are: dVL = (i/C) dt where i = C (dV/dt) of the CMOS FET switches C = load or source capacitance The source must then redistribute this charge, and the effect of source resistance on settling time is shown in the Typical Performance Curves. This graph shows the settling time for a 20V step change on the input. The settling time for smaller step changes on the input will be less than that shown in the curve. MPC508A Channel Source Load Node A RS CS CL RL FIGURE 4. Settling and Common-Mode-Effects— MPC509A Switching Time This is the time required for the CMOS FET to turn ON after a new digital code has been applied to the Channel Address inputs. It is measured from the 50 percent point of the address input signal to the 90 percent point of the analog signal seen at the output for a 10V signal change between channels. Crosstalk Crosstalk is the amount of signal feedthrough from the three (MPC509A) or seven (MPC508A) OFF channels appearing at the multiplexer output. Crosstalk is caused by the voltage divider effect of the OFF channel, OFF resistance and junction capacitances in series with the RON and RS impedances of the ON channel. Crosstalk is measured with a 20Vp-p 1kHz sine wave applied to all OFF channels. The crosstalk for these multiplexers is shown in the Typical Performance Curves. Common-Mode Rejection (MPC509A Only) The matching properties of the load, multiplexer and source affect the common-mode rejection (CMR) capability of a differentially multiplexed system. CMR is the ability of the multiplexer and input amplifier to reject signals that are common to both inputs, and to pass on only the signal difference to the output. For the MPC509A, protection is provided for common-mode signals of ±20V above the power supply voltages with no damage to the analog switches. The CMR of the MPC509A and Burr-Brown’s INA110 instrumentation amplifier is 110dB at DC to 10Hz (G = 100) with a 6dB/octave roll off to 70dB at 1000Hz. This measurement of CMR is shown in the Typical Performance Curves and is made with a Burr-Brown model INA110 instrumentation amplifier connected for gains of 10, 100, and 500. FIGURE 3. Settling Time Effects—MPC508A 6 MPC508A, MPC509A www.ti.com SBFS019A Factors which will degrade multiplexer and system DC CMR are: • • Amplifier bias current and differential impedance mismatch Load impedance mismatch • Multiplexer impedance and leakage current mismatch • Load and source common-mode impedance AC CMR roll off is determined by the amount of commonmode capacitances (absolute and mismatch) from each signal line to ground. Larger capacitances will limit CMR at higher frequencies; thus, if good CMR is desired at higher frequencies, the common-mode capacitances and unbalance of signal lines and multiplexer-to-amplifier wiring must be minimized. Use twisted-shielded-pair signal lines wherever possible. SWITCHING WAVEFORMS Typical at +25°C, unless otherwise noted.

Total package power dissipation must not be exceeded. For best settling speed, the input wiring and interconnections between multiplexer output and driven devices should be kept as short as possible. When driving the digital inputs from TTL, open collector output with pull-up resistors are recommended To preserve common-mode rejection of the MPC509A, use twisted-shielded pair wire for signal lines and inter-tier connections and/or multiplexer output lines. This will help common-mode capacitance balance and reduce stray signal pickup. If shields are used, all shields should be connected as close as possible to system analog common or to the common-mode guard driver. CHANNEL EXPANSION 8 Analog Inputs (CH1 to 8) The ENABLE input, pin 2, is included for expansion of the number of channels on a single node as illustrated in Figure 5. With ENABLE line at a logic 1, the channel is selected by the 2-bit (MPC509A) or 3-bit (MPC508A) Channel Select Address (shown in the Truth Tables). If ENABLE is at logic 0, all channels are turned OFF, even if the Channel Address Lines are active. If the ENABLE line is not to be used, simply tie it to +VSUPPLY.

Single-Node Expansion The 32 x 1 configuration is simply eight (MPC509A) units tied to a single node. Programming is accomplished with a 5-bit counter, using the 2LSBs of the counter to control Channel Address inputs A0 and A1 and the 3MSBs of the counter to drive a 1-of-8 decoder. The 1-of-8 decoder then is used to drive the ENABLE inputs (pin 2) of the MPC509A multiplexers. Two-Tier Expansion Direct 5-Bit To Binary Group Counter 2 1 of 4 Decoder 8 Analog Inputs Up to 32 channels (four multiplexers) can be connected to a single node, or up to 64 channels using nine MPC508A multiplexers on a two-tiered structure as shown in Figures 5 and 6. Using a 4 x 4 two-tier structure for expansion to 16 channels, the programming is simplified. A 4-bit counter output does not require a 1-of-8 decoder. The 2LSBs of the counter drive the A0 and A1 inputs of the four first-tier multiplexers and the 2MSBs of the counter are applied to the A0 and A1 inputs of the second-tier multiplexer. Single vs Multitiered Channel Expansion In addition to reducing programming complexity, two-tier configuration offers the added advantages over single-node expansion of reduced OFF channel current leakage (reduced OFFSET), better CMR, and a more reliable configuration if a channel should fail in the ON condition (short). Should a channel fail ON in the single-node configuration, data cannot be taken from any channel, whereas only one channel group is failed (4 or 8) in the multitiered configuration.
