OPA388, OPA2388, OPA4388 SBOS777 – DECEMBER 2016 OPAx388 Precision, Zero-Drift, Zero-Crossover, True Rail-to-Rail Input/Output, Operational Amplifiers 1 1 Features 1 • 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 – Dual in SOIC-8 and VSSOP-8 – Quad in SOIC-14 and TSSOP-14 2 Applications • Bridge Amplifiers • Strain Gauges • Test Equipment • Current Shunt Measurement • Thermocouples, Thermopiles • Electronic Scales • Medical Instrumentation • Resistor Thermal Detectors • Precision Active Filters 3 Description The OPAx388 (OPA388, OPA2388, and OPA4388) series of precision operational amplifiers 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 only 0.25 µV of offset and 0.005 µV/°C of drift over temperature, makes the OPAx388 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. The OPA2388 (dual version) is offered in the VSSOP-8 and SO-8 packages. The OPA4388 (quad version) is offered in the TSSOP-14 and SO-14 packages. All versions are specified over the extended industrial temperature range (–40°C to +125°C).
