3 Description

The TLV914x family (TLV9141, TLV9142, and

TLV9144) is a family of high voltage (18V) rail-to-rail

input and output (RRIO) operational amplifiers. These

devices offer excellent performance for low-power

applications, because of the family's low quiescent

current of 7μA/channel.

The TLV914x family offers excellent DC precision,

including low offset voltage (±265µV, typical), low

offset drift (±0.2µV/°C, typical), short-circuit current

limit of 40mA, high PSRR of 140dB, and high CMRR

of 108dB for high voltage operation within the main

input pair. The devices are also rated to work at

wide range of supply voltages from 2.7V to 18V.

This makes the TLV914x a flexible, robust, and

high-performance op amp for high-voltage industrial

applications.

These devices also have a gain bandwidth product of

125kHz and low 1/f flicker noise of 3.4µVpeak-to-peak

(0.1Hz to 10Hz). The family was designed to be

able to directly drive capacitive loads up to 350nF,

while maintaining a phase margin of 30 degrees or

higher. The TLV914x op amp family is available in

several industry-standard packages and the devices

are specified from –40°C to 125°C.
