OPA388 Operational Amplifier

Texas Instruments offers its OPA388 precision, zero-drift, zero-crossover, true RRIO operational amplifier

Image of Texas Instruments' OPA388 Operational AmplifierTexas Instruments' OPA388 precision operational amplifier is an ultra-low noise, fast-settling, zero-drift, zero-crossover device that provides rail-to-rail input and output operation. These features and excellent AC performance, combined with only 0.25 µV of offset and 0.005 µV/°C of drift over temperature, make the OPA388 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 superior performance when driving analog-to-digital converters (ADCs) without degradation of linearity. The OPA388 (single version) is available in the VSSOP-8, SOT23-5, and SOIC-8 packages. They are specified over the extended industrial temperature range (-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: 2.5 V to 5.5 V
  • Dual supply: ±1.25 V to ±2.75 V
  • True rail-to-rail input and output
  • EMI/RFI filtered inputs
  • Industry-standard packages:
    • Single in SOIC-8, SOT-23-5, and VSSOP-8
