OPA197 Operational Amplifiers

Texas Instruments offers its OPA197 36 V, precision, rail-to-rail input/output, low offset voltage operational amplifiers

Image of Texas Instruments' OPA197 Operational AmplifiersTexas Instruments' OPA197 family is a new generation of 36 V operational amplifiers. These devices offer outstanding DC precision and AC performance, including rail-to-rail input/output, low offset (±25 µV, typ), low offset drift (±0.25 µV/°C, typ), and 10 MHz bandwidth.

Unique features such as differential input-voltage range to the supply rail, high output current (±65 mA), high capacitive load drive of up to 1 nF, and high slew rate (20 V/µs) make the OPA197 robust, high-performance operational amplifiers for high-voltage, industrial applications. The OPA197 family of op amps is available in standard packages and is specified from -40°C to 125°C.

Features
  • Low offset voltage: ±250 µV (max)
  • Low offset voltage drift: ±2.5 µV/°C (max)
  • Low noise: 5.5 nV//√Hz at 1 kHz
  • High common-mode rejection: 120 dB (min)
  • Low bias current: ±5 pA (typ)
  • Rail-to-rail input and output
  • Wide bandwidth: 10 MHz GBW
  • High slew rate: 20 V/µs
  • Low quiescent current: 1 mA per amplifier (typ)
  • Wide supply: ±2.25 V to ±18 V, 4.5 V to 36 V
  • EMI- and RFI-filtered inputs
  • Differential input voltage range to supply rail
