Description

The LTC2433-1 is a differential input micropower 16-bit No Latency Delta Sigma analog-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.

The converter accepts any external differential reference voltage from 0.1V to VCC for flexible ratiometric and remote sensing measurement configurations. The fullscale differential input range is from – 0.5 • VREF to 0.5 • VREF. The reference common mode voltage, VREFCM, and the input common mode voltage, VINCM, may be independently set anywhere between GND and VCC. The DC common mode input rejection is better than 140dB.

The LTC2433-1 communicates through a flexible 3-wire digital interface which is compatible with SPI and MICROWIRE protocols.
