3 Description

The TLVx172 family of electromagnetic interference

(EMI)-hardened,

36-V,

single-supply,

low-noise

operational amplifiers (op amps) features a THD+N of

0.0002% at 1 kHz with the ability to operate on

supplies ranging from 4.5 V (±2.25 V) to 36 V

(±18 V). These features, along with low noise and

very high PSRR, make the TLVx172 an excellent

choice for microvolt-level signal amplification. The

TLVx172 family of devices offer good offset and drift,

a high bandwidth of 10 MHz, and a slew rate of

10 V/μs with only 2.3 mA (max) of quiescent current

over temperature.

Unlike most operational amplifiers that are specified

at only one supply voltage, the TLVx172 family of

operational amplifiers is specified from 4.5 V to 36 V.

Input signals beyond the supply rails do not cause

phase reversal. The TLVx172 family is stable with

capacitive loads up to 300 pF. The input can operate

100 mV below the negative rail and within 2 V of the

positive rail for normal operation. Note that these

devices can operate with a full rail-to-rail input

100 mV beyond the positive rail, but with reduced

performance within 2 V of the positive rail.

The TLVx172 operational amplifiers are specified

from –40°C to +125°C.
