Low Power Sensor IC

VS1113FE is low-power, low noise 8-channel fully differential or 16 pseudo differential inputs, 24-bit sigma delta analog-to-digital converters with an integrated low-drift internal reference voltage and an integrated PGA with gain ranging from 1 to 128. The ADC interface data integrity features provide for a very low rate of transmission errors. The VS1113FE has very flexible power-supply options. A 2.7V to 3.6V single-supply or ±1.8-V bipolar-supply operation is available. It also provides an integrated low-noise low drift 2.5V reference. The on-chip oscillator or an external clock can be used as the ADC clock source. Data and control communication are handled over a 4MHz , SPI-compatible interface capable of operating with a minimum of three wires.
