description
The TLC274x2 octal operational amplifier
incorporates low offset-voltage drift, high input
impedance, low noise, and speeds approaching
that of general-purpose BiFET devices into a
single package. This device uses Texas
Instruments silicon-gate LinCMOS™ technology,
which provides offset voltage stability far
exceeding the stability available with conventional
metal-gate processes.

The extremely high input impedance, low bias currents, and high slew rates make this a cost-effective device
ideal for applications that have previously been reserved for BiFET and NFET products. These advantages, in
combination with good common-mode rejection and supply-voltage rejection, make this device a good choice
for new state-of-the-art designs as well as for upgrading existing designs.
In general, many features associated with bipolar technology are available on LinCMOS™ operational amplifiers
without the power penalties of bipolar technology. General applications such as transducer interfacing, analog
calculations, amplifier blocks, active filters, and signal buffering are easily designed with the TLC274x2. The
device also exhibits low-voltage single-supply operation, making them ideally suited for remote and inaccessible
battery-powered applications. The common-mode input voltage range includes the negative rail. The device
inputs and outputs are designed to withstand – 100-mA surge currents without sustaining latch-up.
