With integrated 24-bit ADC and 26-bit DSP for linearization and calibration functions, Model ZSSC3224 is designed for consumer barometric pressure and thermopile sensors. Device offers features targeting battery-driven, low-power devices, such as 1 mA typical overall current consumption, ultra-low 20 nA typical sleep mode current, and 1.68–3.6 V power supply range. ZSSC3224 eliminates need for external buffer capacitor and provides PSRR up to 90 dB at 2 V.
