- Part Number:
- LTC2471CDD#PBF
- Manufacturer:
- Linear Technology
- Ventron No:
- 3009188-LTC2471CDD#PBF
- Description:
- IC ADC 16BIT I2C 833SPS 12DFN
- Datasheet:
- LTC2471CDD#PBF
Description
The LTC2471/LTC2473 are 16-bit analog-to-digital converters (ADCs) with an integrated precision reference and a selectable output rate of 208sps or 833sps. They use a single 2.7V to 5.5V supply and communicate through an I²C interface. The LTC2471 is single-ended with a 0V to VREF input range, while the LTC2473 is differential with a ±VREF input range. Both ADCs 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 x 3mm package or an MSOP-12 package. They include an integrated oscillator and perform conversions with no latency for multiplexed applications.
The LTC2471/LTC2473 include 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 LTC2471/LTC2473 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.
The LTC2471/LTC2473 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.
