36-V, Precision, Rail-to-Rail Input Output, Low Offset Voltage Op Amp

36-V, Precision, Rail-to-Rail Input Output, Low Offset Voltage Op Amp - OPA197
 

Description

The OPAx197 family (OPA197, OPA2197, and OPA4197) 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, typical), 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 a robust, high-performance operational amplifier 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: ±100 µV (Maximum)
  • Low Offset Voltage Drift: ±2.5 µV/°C (Maximum)
  • Low Noise: 5.5 nV/√Hz at 1 kHz
  • High Common-Mode Rejection: 120 dB (Minimum)
  • Low Bias Current: ±5 pA (Typical)
  • Rail-to-Rail Input and Output
  • Wide Bandwidth: 10-MHz GBW
  • High Slew Rate: 20 V/µs
  • Low Quiescent Current: 1 mA per Amplifier (Typical)
  • 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
  • High Capacitive Load Drive Capability: 1 nF
  • Industry Standard Packages:
    • Single in SOIC-8, SOT-5, and VSSOP-8
    • Dual in SOIC-8 and VSSOP-8
    • Quad in SOIC-14 and TSSOP-14
