LTC2433-1IMS#PBF

LTC®2433-1 is a differential input micropower 16bit No Latency ∆Σ™ analogue-to-digital converter with an integrated oscillator. It provides 0.12LSB INL and 1.45µV RMS noise independent of VREF. It uses delta-sigma technology and provides single conversion settling of the digital filter. Through a single pin, the LTC2433-1 can be configured for better than 87dB input differential mode rejection at 50Hz and 60Hz ±2%, or it can be driven by an external oscillator for a user-defined rejection frequency. The internal oscillator requires no external frequency setting components. Typical applications include direct sensor digitizer, weight scales, direct temperature measurement, gas analysers, strain-gauge transducers, instrumentation, data acquisition and industrial process control.
