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.
