Overview

The LTC2470/LTC2472 are small, 16-bit analog-to-digital converters with an integrated precision reference and a selectable 208sps or 833sps output rate. They use a single 2.7V to 5.5V supply and communicate through a SPI Interface. The LTC2470IMS#PBF is single-ended with a 0V to VREF input range and the LTC2472 is differential with a ±VREF input range. Both ADC’s include a 1.25V integrated reference with 2ppm/°C drift performance and 0.1% initial accuracy. The converters are available in a 12-pin DFN 3mm × 3mm package or an MSOP-12 package. They include an integrated oscillator and perform conversions with no latency for multiplexed applications. The LTC2470/ LTC2472 include a proprietary input sampling scheme that reduces the average input current several orders of magnitude when compared to conventional delta sigma converters.

The LTC2470/LTC2472 include a user selectable 208sps or 833sps output rate and due to a large oversampling ratio (8,192 at 208sps and 2,048 at 833sps) have relaxed anti-aliasing requirements.
