OPA4388 Precision Op-Amp

Texas Instruments' zero-drift, zero-crossover, true RRIO op-amps are ideal for general purpose and precision applications

Image of Texas Instruments' OPA4388 Precision Op-AmpTexas Instruments' OPA4388 precision op-amps are ultra-low noise, fast-settling, zero-drift, zero-crossover devices that provide rail-to-rail input and output operation. These features and excellent AC performance, combined with 0.25 µV offset and 0.005 µV/°C drift overtemperature makes the OPA4388 ideal for driving high-precision, analog-to-digital converters (ADCs) or buffering the output of high-resolution, digital-to-analog converters (DACs). This design results in excellent performance when driving ADCs without degradation of linearity. The OPA4388 (quad) is offered in the TSSOP-14 and SO-14 packages. The op-amps are specified over the industrial temperature range of -40°C to +125°C.

Features
  • Ultra-low offset voltage: ±0.25 µV
  • Zero drift: ±0.005 µV/°C
  • Zero crossover: 140 dB CMRR true RRIO
  • Low noise: 7.0 nV√Hz at 1 kHz
  • No 1/f noise: 140 nVPP (0.1 Hz to 10 Hz)
  • Fast settling: 2 µs (1 V to 0.01%)
  • Gain bandwidth: 10 MHz
  • Single supply: ±1.25 V to ±2.75 V
  • True rail-to-rail input and output
  • EMI/RFI filtered inputs
  • Industry-standard packages: SOIC-14 and TSSOP-14
Applications
  • Bridge amps
  • Strain gauges
  • Test equipment
  • Current shunt measurement
  • Thermocouples, thermopiles
  • Electronic scales
  • Medical instrumentation
  • Resistor thermal detectors
  • Precision active filters
