TSV791 Rail-to-Rail 5 V Op Amp

STMicroelectronics’ single 50 MHz bandwidth unity-gain-stable amp features rail-to-rail input stage

STMicroelectronics’ TSV791 is a single 50 MHz bandwidth unity gain stable amplifier. The rail-to-rail input stage and the slew rate of 30 V/μs make the TSV791 ideal for low-side current measurement. The excellent accuracy provided by a maximum input voltage of 200 μV allows amplifying accurately small-amplitude input signal. The TSV791 can operate from a 2.2 V to 5.5 V single supply, and it is designed to allow easy usage as A/D converters’ input buffer.


  • Gain bandwidth product 50 MHz, unity gain stable
  • Slew rate 30 V/µs
  • Low input offset voltage 50 µV typ, 200 µV max
  • Low input bias current: 2 pA typ
  • Low input voltage noise density 6.5 nV/√Hz
  • Wide supply voltage range: 2.2 V to 5.5 V
  • Rail-to-rail input and output
  • Accuracy of measurement virtually unaffected by noise or input bias current
  • Signal conditioning for high frequencies
