OPA2365
Overview
The OPA365 and OPA2365 (OPAx365) zerøcrossover series, rail-to-rail, high-performance, CMOS operational amplifiers are optimized for very low R2 2kΩ voltage, single-supply applications. Rail-to-rail input or output, low-noise (4.5 nV/√Hz), and high-speed operation (50-MHz gain bandwidth) make these devices an excellent choice for driving sampling analog-to-digital converters (ADCs).
- Gain bandwidth: 50 MHz
- Zerø-crossover distortion topology: - Excellent THD+N: 0.0004% - CMRR: 100 dB (minimum) - Rail-to-rail input and output
- Input 100 mV beyond supply rail
- Low noise: 4.5 nV/√Hz at 100 kHz
- Slew rate: 25 V/µs
- Fast settling: 0.3 μs to 0.01%
- Precision: - Low offset: 100 µV - Low input bias current: 0.2 pA
- 2.2-V to 5.5-V operation
