LTC2449IUHF 24-Bit High Speed Analog to Digital Converter with SPI Interface QFN-38
The LTC2449IUHF is an 8-/16-channel high speed 24-bit No Latency ∆Σ™ ADC. It utilizes a proprietary delta-sigma architecture that enables variable speed/resolution. Through a simple 4-wire serial interface, ten speed/resolution combinations from 6.9Hz/280nVRMS to 3.5kHz/25µVRMS (4kHz with external oscillator) can be selected with no latency between conversion results or shift in DC accuracy (offset, full-scale, linearity, drift).
