FEATURES  
DESCRIPTION

•
Intelligent Monitoring:  
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.

Every 1ms → 25mW  
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.  
Every 10ms → 5mW  
< 1µA of Power-Down Current

–
Auto Power-Down Control  
PWRCON Pin Allows Shutdown of External  
Op Amp  
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  
10ms. An onboard oscillator eliminates the need to  
supply a master clock.  
•
•
Wide Supply Range:  
–
–
Analog Supply: 2.2V to 5.5V  
Digital Supply: 1.65V to 5.5V  
Small Footprint: 3mm × 3mm QFN  
APPLICATIONS  
The ADS7924 is offered in a small 3mm × 3mm QFN  
and is fully specified for operation over the industrial  
temperature range of –40°C to +85°C.
