Description
General part information
ADS7924 Series
The ADS7924 is a four-channel, 12-bit, analog-to-digital converter (ADC) with an I2C™ interface. With its low-power ADC core, support for low-supply operation, and a flexible measurement sequencer that essentially eliminates power consumption between conversions, the ADS7924 forms a complete monitoring system for power-critical applications such as battery-powered equipment and energy harvesting systems.
The ADS7924 features dedicated data registers and onboard programmable digital threshold comparators for each input. Alarm conditions can be programmed that generate an interrupt. The combination of data buffering, programmable threshold comparisons, and alarm interrupts minimize the host microcontroller time needed to supervise the ADS7924.
The four-channel input multiplexer (MUX) is routed through external pins to allow a common signal conditioning circuit to be used between the MUX and ADC, thereby reducing overall component count. The low-power ADC uses the analog supply as its reference and can acquire and convert signals in only 10 µs. An onboard oscillator eliminates the need to supply a master clock.
