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 ultra-low 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-of-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 HBV).
