ADS7229IRSAT

Analog To Digital Converters (ADC) Overview

The ADS7229IRSAT is a low-power, 12-bit analog-to-digital converter (ADC) manufactured by Texas Instruments. It features a single-channel successive approximation register (SAR) architecture with an integrated sample-and-hold circuit. The device supports a sampling rate of 1 MSPS and operates with an analog supply voltage range of 2.7V to 5.5V and a digital I/O supply range of 1.65V to 5.5V. It utilizes an external reference type and communicates via a high-speed SPI/DSP compatible serial interface. The component is housed in a 16-VQFN package with dimensions of 4x4 mm and is rated for operation within a temperature range of -40°C to +85°C.

• Provides programmable TAG bit output options and software reset capability

Analog To Digital Converters (ADC) Applications

• Data acquisition systems
• Industrial process control
• Medical devices
• Transducer interfaces

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IRSAT corresponds to the 16-QFN package and industrial temperature grade during sourcing. Confirm RoHS3 compliance status as required by project specifications. Ensure the external reference voltage matches the device's input requirements for optimal performance. Check for availability of equivalent packages if lead times are critical.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel, 12-bit resolution is sufficient for the application. Consider the ADS7230 variant if dual-channel input capability is required instead of single-ended inputs. Evaluate power consumption requirements against the 13.7mW typical dissipation at 1MHz sampling. Ensure the system design accommodates the 16-VQFN footprint and thermal dissipation needs.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS7229/ADS7230 family of low-power data converters from Texas Instruments. The series is designed for applications requiring moderate speed and resolution with minimal power consumption. The ADS7229 specifically focuses on single-channel performance, distinguishing it from the dual-channel ADS7230 within the same product line.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS7230IRSAR is documented as a parameter-equivalent alternative. Verify channel count differences as the ADS7230 offers two inputs compared to the single input of the ADS7229.
