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.
