OPA320AIDBVT

Low Offset Voltage: 150 μV (Maximum) High CMRR: 114 dB Rail-to-Rail I/O The OPA320 (single) and OPA2320 (dual) are a new generation of precision, low-voltage CMOS operational amplifiers optimized for very low noise and wide bandwidth while operating on a low quiescent current of only 1.45 mA. The OPA320 series is ideal for low-power, single-supply applications. Low-noise (7 nV/√Hz) and high-speed operation also make them well-suited for driving sampling analog-to-digital converters (ADCs). Other applications include signal conditioning and sensor amplification. Low Input Bias Current: 0.9 pA (Maximum) Low Noise: 7 nV/√Hz at 10 kHz Wide Bandwidth: 20 MHz Slew Rate: 10 V/μs Quiescent Current: 1.45 mA/Ch Single-Supply Voltage Range: 1.8 V to 5.5 V OPA320S and OPA2320S: – IQ in Shutdown Mode: 0.1 μA Unity-Gain Stable Small Packages: – SOT-23, VSSOP, SON, and SOIC The OPA320 features a linear input stage with zero-crossover distortion that delivers excellent common-mode rejection ratio (CMRR) of typically 114 dB over the full input range. The input common mode range extends 100 mV beyond the negative and positive supply rails. The output voltage typically swings within 10 mV of the rails.
