The TLC252, TLC25L2, and TLC25M2 are

–
low-cost, low-power dual operational amplifiers
designed to operate with single or dual supplies.
These devices utilize the Texas Instruments
silicon gate LinCMOS process, giving them stable input offset voltages that are available in selected grades
of 2, 5, or 10 mV maximum, very high input impedances, and extremely low input offset and bias currents.
Because the input common-mode range extends to the negative rail and the power consumption is extremely
low, this series is ideally suited for battery-powered or energy-conserving applications. The series offers
operation down to a 1.4-V supply, is stable at unity gain, and has excellent noise characteristics.
These devices have internal electrostatic-discharge (ESD) protection circuits that prevent catastrophic failures
at voltages up to 2000 V as tested under MIL-STD-883C, Method 3015.1. However, care should be exercised
in handling these devices as exposure to ESD may result in a degradation of the device parametric
performance.

description (continued)
Because of the extremely high input impedance and low input bias and offset currents, applications for the
TLC252/ 25_2 series include many areas that have previously been limited to BIFET and NFET product types.
Any circuit using high-impedance elements and requiring small offset errors is a good candidate for
cost-effective use of these devices. Many features associated with bipolar technology are available with
LinCMOS operational amplifiers without the power penalties of traditional bipolar devices. General
applications such as transducer interfacing, analog calculations, amplifier blocks, active filters, and signal
buffering are all easily designed with the TLC252 / 25_2 series devices. Remote and inaccessible equipment
applications are possible using their low-voltage and low-power capabilities. The TLC252 / 25_2 series is well
suited to solve the difficult problems associated with single-battery and solar-cell-powered applications. This
series includes devices that are characterized for the commercial temperature range and are available in 8-pin
plastic dip and the small-outline package. The device is also available in chip form.
The TLC252 / 25_2 series is characterized for operation from 0°C to 70°C.

PARAMETER MEASUREMENT INFORMATION
single-supply versus split-supply test circuits
Because the TLC252, TLC25L2, and TLC25M2 are optimized for single-supply operation, circuit configurations
used for the various tests often present some inconvenience since the input signal, in many
cases, must be offset from ground. This inconvenience can be avoided by testing the device with split supplies
and the output load tied to the negative rail. A comparison of single-supply versus split-supply test circuits is
shown below. The use of either circuit gives the same result.

APPLICATION INFORMATION
latch-up avoidance
Junction-isolated CMOS circuits have an inherent parasitic PNPN structure that can function as an SCR. Under
certain conditions, this SCR may be triggered into a low-impedance state, resulting in excessive supply current.
To avoid such conditions, no voltage greater than 0.3 V beyond the supply rails should be applied to any pin.
In general, the operational amplifier supplies should be applied simultaneously with, or before, application of
any input signals.
output stage considerations
The amplifier’s output stage consists of a source-follower-connected pullup transistor and an open-drain
pulldown transistor. The high-level output voltage (VOH) is virtually independent of the IDD selection and
increases with higher values of VDD and reduced output loading. The low-level output voltage (VOL) decreases
with reduced output current and higher input common-mode voltage. With no load, VOL is essentially equal to
the potential of VDD – /GND.
supply configurations
Even though the TLC252 / 25_2C series is characterized for single-supply operation, it can be used effectively
in a split-supply configuration if the input common-mode voltage (VICR), output swing (VOL and VOH), and supply
voltage limits are not exceeded.
circuit layout precautions
The user is cautioned that whenever extremely high circuit impedances are used, care must be exercised in
layout, construction, board cleanliness, and supply filtering to avoid hum and noise pickup, as well as excessive
dc leakages.
