Overview
The TSV912 from Texas Instruments is a dual-channel operational amplifier (op amp) designed for general-purpose applications. It is part of the TSV91x family, which includes single-, dual-, and quad-channel op amps. This device is notable for its rail-to-rail input and output (RRIO) swings, wide bandwidth of 8 MHz, and low offset voltage, making it suitable for a variety of applications requiring a balance between speed and power consumption.
The TSV912 is unity-gain stable and features an ultra-low input bias current, enabling its use in applications with high-source impedances, such as sensor interfaces, battery-supplied and portable applications, and active filtering. The robust design includes integrated RFI-EMI rejection filters, no phase reversal in overdrive conditions, and high electrostatic discharge (ESD) protection of ±4-kV human-body model (HBM).
