LTC2471CMS#PBF

LTC®2471 is small analogue-to-digital converter with an integrated precision reference and a selectable 208sps output rate. This use a single 2.7V to 5.5V supply and communicate through an I²C Interface. It include a proprietary input sampling scheme that reduces the average input current several orders of magnitude when compared to conventional delta sigma converters. It 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. Applications are system monitoring, environmental monitoring, Direct temperature measurements, Instrumentation, Industrial process control, Data acquisition, Embedded ADC upgrades.

• Include 1.25V integrated reference with 2ppm/°C drift performance and 0.1% initial accuracy
• Single-ended with a 0V to VREF input range
• 16-bit resolution
• 1mV offset error
• 0.01% gain error
• Single conversion settling time simplifies multiplexed applications
• Single-cycle operation with auto shutdown
• 3.5mA (typical) supply current, 2µA (maximum) sleep current
• Internal oscillator-no external components required
• 12-lead plastic MSOP, 0°C to 70°C temperature range
