Texas Instruments OPA320 / OPA2320 20MHz CMOS Op Amps

TI OPA320 / OPA2320 20MHz CMOS Op Amps

Texas Instruments OPA320 single-channel and OPA2320 dual-channel 20MHz CMOS op amps are optimized for very low noise and wide bandwidth while operating on a low quiescent current of only 1.45mA. TI OPA320 and OPA2320 op amps are ideal for low-power, single-supply applications. Low noise (7nV/√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. These TI op amps feature a linear input stage with zero-crossover distortion that delivers excellent common-mode rejection ration of typically 114dB over the full input range. The input common-mode range extends 100mV beyond the negative and positive supply rails. The output voltage typically swings within 10mV of the rails. OPA320 and OPA2320 devices have a wide supply voltage range from 1.8V to 5.5V with excellent PSRR (106dB) over the entire supply range.
