LTC2449: 24-Bit High Speed 16-Channel Delta Sigma ADCs with Selectable Speed/Resolution.
The LTC2449 is a 16-channel (8-differential) high speed 24-bit No Latency Delta Sigma ADCs. They use a proprietary delta-sigma architecture enabling variable speed/resolution. Through a simple 4-wire serial interface, ten speed/resolution combinations 6.9Hz/280nVRMS to 3.5kHz/25uVRMS (4kHz with external oscillator) can be selected with no latency between conversion results or shift in DC accuracy (offset, full-scale, linearity, drift). Additionally, a 2X speed mode can be selected enabling output rates up to 7kHz (8kHz if an external oscillator is used) with one cycle latency.
