Data sheet:
The OPAx397 family of operational amplifiers (OPA397, OPA2397, and OPA4397) features ultra-low offset, offset drift, and input bias current with rail-to-rail input and output operation. In addition to precision dc accuracy, the ac performance is optimized for low noise and fast-settling transient response. These features make the OPAx397 an excellent choice for driving high-precision analog-to-digital converters (ADCs) or buffering the output of high-resolution, digital-to-analog converters (DACs).
The OPAx397 feature TI’s e-trim™ operational amplifier technology to achieve ultra-low offset voltage and offset voltage drift without any input chopping or auto-zero techniques. This technique enables ultra-low input bias current for sensor inputs or photodiode current-to-voltage measurements, creating high-performance transimpedance stages for optical modules or medical instrumentation.
- Low offset voltage: ±60µV (maximum)
- Low-drift: ±0.18µV/°C
- Low input bias current: 10fA
- Low noise: 4.4nV√Hz at 10kHz
- Low 1/f noise: 2µVPP (0.1Hz to 10Hz)
- Low supply voltage operation: 1.7V to 5.5V
- Low quiescent current: 1.22mA
- Fast settling: 0.75µs (1V to 0.1%)
- Fast slew rate: 4.5V/µs
- High output current: +65/-55mA short circuit
- Gain bandwidth: 13MHz
- Rail-to-rail input and output
- Specified temperature range: –40°C to +125°C
- EMI/RFI filtered inputs
