Product Details

The LTC2436-1 is a 2-channel differential input micropower 16-bit No Latency ∆Σ analog-to-digital converter with an integrated oscillator. It provides 0.5LSB INL and 800nV RMS noise independent of VREF. The two differential channels convert alternately with a channel identification included in the conversion result. It uses delta-sigma technology and provides single conversion settling of the digital filter. Through a single pin, the LTC2436-1 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 full-scale 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 LTC2436-1 communicates through a flexible 3-wire digital interface which is compatible with SPI and MICROWIRE protocols.
