LTC2472IMS#PBF

LTC2472 is a small, 16-bit analogue-to-digital converter with an integrated precision reference. This use a single 2.7V to 5.5V supply and communicate through a SPI Interface. This is single-ended with a 0V to VREF input range. This ADC includes a 1.25V integrated reference with 2ppm/°C drift performance and 0.1% initial accuracy. This includes an integrated oscillator and perform conversions with no latency for multiplexed applications. It includes a proprietary input sampling scheme that reduces the average input current several orders of magnitude when compared to conventional delta sigma converters. This automatically power down the converter and can also be configured to power down the reference. When ADC and reference are powered down, the supply current is reduced to 200nA. Typical applications are system monitoring, environmental monitoring, direct temperature measurements, instrumentation, industrial process control, data acquisition, embedded ADC upgrades.

• Differential with a ±VREF input range
• 1mV offset error, 0.01% gain error
• Single conversion settling time for multiplexed applications
• 3.5mA (typ) supply current, 2µA (max) sleep current, single-cycle operation with auto shutdown
• Internal oscillator-no external components required, SPI interface
• Integral nonlinearity is 8.5LSB (output rate 208sp, TA=25°C)
• Offset error is ±2.5mV (TA=25°C)
• 12-lead plastic MSOP package
• Temperature rating range from –40°C to 85°C
