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 (±18V).

These features, along with low noise and very high

PSRR, enable the TLVx172 to amplify microvolt-level

signals in applications such as HEV and EV

automobiles and power trains, medical

instrumentation, and more. The TLVx172 device

offers good offset and drift, a high bandwidth of 10

MHz, and a slew rate of 10 V/μs with only 2.3 mA of

quiescent current over temperature (maximum).

Unlike most op amps that are specified at only one

supply voltage, the TLVx172 device is specified from

4.5 V to 36 V. Input signals beyond the supply rails

do not cause phase reversal. TLVx172 device 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 the device 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 op amp is specified from .40°C to

+125°C.
