3 Description

The 36-V TLVx171 family provides a low-power

option for cost-conscious industrial and personal

electronics systems requiring an electromagnetic

interference (EMI)-hardened, low-noise, single-supply

operational amplifier (op amp) that operates on

supplies ranging from 2.7 V (±1.35 V) to 36 V

(±18 V). The single-channel TLV171, dual-channel

TLV2171, and quad-channel TLV4171 provide low

offset, drift, quiescent current balanced with high

bandwidth for the power. The devices are available in

micropackages for space-constrained systems and

feature identical specifications for maximum design

flexibility.

Unlike most op amp, which are specified at only one

supply voltage, the TLVx171 family is specified from

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

do not cause phase reversal. The TLVx171 family is

stable with capacitive loads up to 200 pF. The input

can operate 100 mV below the negative rail and

within 2 V of the top rail during normal operation.

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

100 mV beyond the top rail, but with reduced

performance within 2 V of the top rail.

The TLVx171 op amp family is specified from –40°C

to +125°C.
