Details
The ADS7924IRTET 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.

FAQs
What is ADS7924IRTET?
The ADS7924IRTET is a 12-bit, 4-channel analog-to-digital converter (ADC) designed by Texas Instruments. It is suitable for applications requiring multiple input channels and medium resolution conversion, such as industrial automation, data acquisition, and sensor interfaces.
How Does ADS7924IRTET Work?
The ADS7924IRTET operates by converting analog input signals from up to 4 channels into digital data with 12-bit resolution. It features a successive approximation register (SAR) architecture for fast and accurate conversion. The ADC provides programmable sequencing of input channels and a flexible interface for easy integration into various systems.
How Many Pins does ADS7924IRTET have and What are the Functions of the Pinout Configuration?
The ADS7924IRTET is housed in a 16-lead WQFN (Wide Quad Flat No-Lead) package. The pinout configuration includes:
- AIN0-AIN3: Analog input channels.
- AVDD, DVDD: Analog and digital power supply pins.
- AGND, DGND: Analog and digital ground pins.
- CS, SDI, SDO, SCLK: Serial interface control pins.
- CONVST: Conversion start control pin.
- EOC: End of conversion output pin.
What are the Pros and Cons of ADS7924IRTET?
Pros:
- Multiple Channels: Provides 4 input channels for simultaneous or sequential measurements.
- 12-Bit Resolution: Offers medium resolution for accurate digital conversion.
- Programmable Sequencing: Allows flexibility in channel selection and order.
- Fast Conversion: Utilizes SAR architecture for quick conversion times.
- Small Package: The 16-lead WQFN package is space-efficient for compact designs.
Cons:
- Resolution Limitation: May not be suitable for applications requiring higher resolution ADCs.
- Input Range: Limited input voltage range compared to some higher-end ADCs.
- No Internal Reference: Requires external reference voltage for operation.
Are There Any Equivalents/Alternatives to ADS7924IRTET for Recommendation?
- The ADS7886 from Texas Instruments is a similar 12-bit, 8-channel ADC suitable for multi-channel applications.
- Alternatives to the ADS7924IRTET include the MCP3204 from Microchip Technology and the MAX1237 from Maxim Integrated.
