OPA4191 Low-power Precision e-trim™ CMOS Amp

Texas Instruments' 36 V, rail-to-rail input/output, low offset voltage amp offers outstanding DC precision and AC performance

Image of Texas Instruments' OPA4191 e-trim™ CMOS AmpTexas Instruments' OPA4191 36 V, e-trim™ op-amp offers outstanding DC precision and AC performance including rail-to-rail input/output, low offset voltage (±5 µV typical), low offset drift (±0.2 µV/°C typical), and 2 MHz bandwidth. Unique features such as a differential input-voltage range to the supply rail, high output current (±65 mA), high capacitive load drive (up to 1 nF), and high slew rate (5 V/µs) make the OPA4191 a robust, high-performance op-amp for high-voltage industrial applications. The OPA4191 op-amp is available in standard packages and is specified for a -40°C to +125°C temperature range.

Features
  • Low offset voltage: ±5 µV
  • Low offset voltage drift: ±0.1 µV/°C
  • Low noise: 15 nV/√Hz at 1 kHz
  • High common-mode rejection: 140 dB
  • Low bias current: ± 5 pA
  • Rail-to-rail input and output
  • Wide bandwidth: 2.5 MHz GBW
  • High slew rate: 5 V/µs
  • Low quiescent current: 140 µA per amp
  • Wide supplies: ±2.25 V to ±18 V, 4.5 V to 36 V
  • EMI/RFI filtered inputs
  • Differential input voltage range to supply the rail
  • High capacitive load drive capability: 1 nF
  • Industry-standard packages: SOIC-14, TSSOP-14, and WQFN-16
Applications
  • Analog input modules
  • Mixed modules (AI, AO, DI, and DO)
  • Data acquisition (DAQ)
  • Source measurement units (SMUs)
  • Pressure transmitters
  • Train controls and management systems
  • Lab and field instrumentation
