LTC2470IMS#PBF

LINEAR TECHNOLOGY  LTC2470IMS#PBF  模数转换器, 16 bit, 250 SPS, 单, 2.7 V, 5.5 V, MSOP

The is a 16-bit single-ended Analog-to-digital Converter ADC with an integrated precision reference. They use a single 2.7 to 5.5V supply and communicate through a SPI Interface. The ADC is single-ended with a 0V to VREF input range and this is differential with a ±VREF input range. It includes an integrated oscillator and performs conversions with no latency for multiplexed applications. The ADC includes a proprietary input sampling scheme that reduces the average input current several orders of magnitude when compared to conventional delta sigma converters. Following a single conversion, the ADC automatically power down the converter and can also be configured to power down the reference. When both the ADC and reference are powered down, the supply current is reduced to 200nA. It includes user selectable 208/833sps output rate and due to a large oversampling ratio have relaxed anti-aliasing requirements.
