3 Description

The TSV91xA-Q1 family, which includes single-,

dual-, and quad-channel operational amplifiers (op

amps), is specifically designed for general-purpose

automotive applications. Featuring rail-to-rail input

and output (RRIO) swings, wide bandwidth (8

MHz), and low offset voltage (0.3 mV, typical), this

family is designed for a variety of applications that

require a good balance between speed and power

consumption. The op amps are unity-gain stable and

feature an ultra-low input bias current, which enables

the family to be used in applications with high-source

impedance. The low input bias current allows the

devices to be used for sensor interfaces, and active

filtering.

The robust design of the TSV91xA-Q1 provides easeof-

use to the circuit designer. Features include a

unity-gain stable, integrated RFI-EMI rejection filter,

no phase reversal in overdrive condition, and high

electrostatic discharge (ESD) protection (4-kV HBM).
