description

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.
