The ADS7924 is a four-channel, 12-bit, analog-to-digital converter (ADC) with anI2C™ interface. Withits low-power ADC core, support for low-supply operation, and a flexible measurement sequencer thatessentially eliminates power consumption between conversions, the ADS7924 forms a completemonitoring system for power-critical applications such as battery-powered equipment and energyharvesting systems.

The ADS7924 features dedicated data registers and onboard programmable digital thresholdcomparators for each input. Alarm conditions can be programmed that generate an interrupt. Thecombination of data buffering, programmable threshold comparisons, and alarm interrupts minimizethe host microcontroller time needed to supervise the ADS7924.

The four-channel input multiplexer (MUX) is routed through external pins to allow acommon signal conditioning circuit to be used between the MUX and ADC, thereby reducing overallcomponent count. The low-power ADC uses the analog supply as its reference and can acquire andconvert signals in only 10 µs. An onboard oscillator eliminates the need to supply a masterclock.

The ADS7924 is offered in a small 3-mm × 3-mm WQFN and is fully specified for operationover the industrial temperature range of –40°C to 85°C.
