The TLC2801 is a precision, low-noise
operational amplifier manufactured using Texas
Instruments Advanced LinCMOS™ process. The
TLC2801 combines the noise performance of the
lowest-noise JFET amplifiers with the dc precision
available previously only in bipolar amplifiers. The
Advanced LinCMOS™ process uses silicon-gate
technology to obtain input offset voltage stability
with temperature and time that far exceeds that
obtainable using metal-gate technology. In
addition, this technology makes possible input
impedance levels that meet or exceed levels
offered by top-gate JFET and expensive
dielectric-isolated devices.

The combination of excellent dc and noise
performance with a common-mode input voltage
range that includes the negative rail makes the
TLC2801 an ideal choice for high-impedance,
low-level signal conditioning applications in either
single-supply or split-supply configurations.
The device inputs and output are designed to
withstand – 100-mA surge currents without
sustaining latch-up. In addition, internal ESD-
protection circuits prevent functional failures at
voltages up to 2000 V as tested under
MIL-STD-883C, Method 3015.2; however, care
should be exercised in handling these devices as
exposure to ESD may result in degradation of the
device parametric performance.
The TLC2801 is characterized for operation over
the temperature range of – 40°C to 150°C.
