ADS7829IDRBT

Analog To Digital Converters (ADC) Overview

The ADS7829IDRBT is a 12-bit successive approximation register (SAR) analog-to-digital converter (ADC) from Texas Instruments. It features a single pseudo-differential input and operates on an external reference. The device supports a sampling rate of 200 kSPS with a power consumption of 800 µW. It functions within a supply voltage range of 2.7 V to 5.25 V for both analog and digital domains. The component is housed in an 8-SON package with dimensions of 3x3 mm. It operates across a temperature range of -40°C to +85°C.

• Medical equipment signal conditioning

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'BT' corresponds to the tape and reel packaging configuration as indicated by distributor listings. Confirm that the external reference requirement aligns with system design constraints, as internal references are not available in this variant. Ensure compatibility with the 8-SON package footprint during PCB layout verification.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 12-bit resolution is required alongside high-speed sampling at 200 kSPS. It is appropriate for designs needing low power consumption under 1 mW. Consider the external reference requirement if precision is critical. The wide supply voltage range allows flexibility in system power architecture without level shifting.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS7826/7827/7828/7829 family of micro-power ADCs. While sharing similar interfaces and architectures, the ADS7829 specifically offers 12-bit resolution compared to lower resolutions in other family members. It maintains the same compact 8-SON package and low-power characteristics typical of the series.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS7829IDRBR is an alternative packaging option for the same functional device. Other family members like ADS7826 or ADS7827 offer different resolutions but share similar pinouts and interfaces. Verify performance differences before substitution.
