OP213FSZ

OP213 is a low noise, low drift single-supply operational amplifier. It has been designed for systems with internal calibration. Often this processor-based systems are capable of calibrating corrections for offset and gain, but they cannot correct for temperature drifts and noise. Optimized for these parameters, It can be used to take advantage of superior analogue performance combined with digital correction. Digital scales and other strain gauge applications benefit from the very low noise and low drift of the device family. Other applications include use as a buffer or amplifier for both analogue-to-digital (ADC) and digital-to-analogue (DAC) sigma-delta converters. Often this converter has high resolutions requiring the lowest noise amplifier to utilize their full potential. It is widely used in application such as digital scales, multimedia, strain gauges, battery-powered instrumentation, temperature transducer amplifier- etc.
