description
The TLC254, TLC254A, TLC254B, TLC25L4,
TLC254L4A, TLC254L4B, TLC25M4, TLC25M4A
and TL25M4B are low-cost, low-power quad
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 degradation of the device parametric performance.
Because of the extremely high input impedance and low input bias and offset currents, applications for these
devices 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.

description (continued)
General applications such as transducer interfacing, analog calculations, amplifier blocks, active filters, and
signal buffering are all easily designed with these devices. Remote and inaccessible equipment applications
are possible using their low-voltage and low-power capabilities. These devices are 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 14-pin plastic dip and
the small-outline packages. The device is also available in chip form.
These devices are characterized for operation from 0°C to 70°C.

PARAMETER MEASUREMENT INFORMATION
single-supply versus split-supply test circuits
Because the TLC25_4, TLC25_4A, and TLC25_4B 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 amplifiers supplies should be established 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 V
DD–
/GND.
supply configurations
Even though the TLC25_4C series is are characterized for single-supply operation, they can be used effectively
in a split-supply configuration if the input common-mode voltage (V
ICR
), output swing (VOL and VOH), and supply
voltage limits are not exceeded.
circuit layout precautions
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.
