TSV91x -TSV99x
Rail-to-rail CMOS inputs operational amplifiers

TSV91x datasheet TSV99x datasheet ST has brought out two new families of low voltage single, dual and quad op-amps, the TSV911/2/4 and TSV991/2/4. Rail-to-rail in both input and output, and offering up to 20MHz of bandwidth, these multi-segment products provide an excellent speed/consumption ratio. Their supply range extends from 2.5V up to 5.5V. Rail-to-rail configurations both at input and output provide an improved dynamic range in low voltage applications.

The new TSV91x and TSV99x families feature CMOS inputs with a bias current of only 1pA (typical value, 10pA maximum), making them ideal for high impedance sensor signal conditioning. The high merit factor of these op-amps allows for relatively low consumption while providing a high gain bandwidth product at 2.5V. These two families have exceptional tolerance to ESD, sustaining 5kV in human body model. Their low consumption and their ability to deliver signals very close to the rails (15mV typ) make them very useful in low voltage and portable applications. Their stable DC performances on a wide range of temperatures (-40°C to + 125°C) associated with their low input bias current will perfectly fit to sensor signal conditioning in industrial and automotive applications.

A slew rate of 10V/µs for TSV99x is also highly appreciated in current control loop where signals variations can be fast. They are housed in the SOT23-5 or SO-8 packages (for the single versions), MiniSO-8 and SO-8 (for dual versions) and TSSOP14, SO-14 packages (for quad versions).
