3 Description

The TSV91x family, which includes single-, dual-, and

quad-channel operational amplifiers (op amps), is

specifically designed for general-purpose

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 ultralow

input bias current, which enables the family to be

used in applications with high-source impedances.

The low input bias current allows the devices to be

used for sensor interfaces, battery-supplied and

portable applications, and active filtering.

The robust design of the TSV91x provides ease-ofuse

to the circuit designer. Features include a unitygain

stable, integrated RFI-EMI rejection filter, no

phase reversal in overdrive condition, and high

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