description
The TLC220x, TLC220xA, TLC220xB, and
TLC220xY are precision, low-noise operational
amplifiers using Texas Instruments Advanced
LinCMOS™ process. These devices combine 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 these
devices an ideal choice for high-impedance,
low-level signal-conditioning applications in either
single-supply or split-supply configurations.

The device inputs and outputs 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-PRF-38535, Method 3015.2; however, care should be exercised in handling these devices as exposure
to ESD may result in degradation of the parametric performance.
The C-suffix devices are characterized for operation from 0°C to 70°C. The I-suffix devices are characterized
for operation from – 40
°C
to 85°C. The M-suffix devices are characterized for operation over the full military
temperature range of – 55°C to 125°C.
