ADS7959SRGET

Analog To Digital Converters (ADC) Overview

The ADS7959SRGET is an 8-bit, 1 MSPS successive approximation register (SAR) analog-to-digital converter (ADC) manufactured by Texas Instruments. It features eight single-ended input channels and utilizes a VQFN-24 package for surface-mount installation. The device operates with an analog supply voltage range of 2.7 V to 5.25 V and a digital supply voltage range of 1.7 V to 5.25 V. Key performance metrics include a signal-to-noise ratio (SNR) of 49 dB, a signal-to-noise and distortion ratio (SINAD) of 49 dB, and an integral nonlinearity (INL) of 0.12% FSR. Power consumption is specified at 11.5 mW, with a maximum power dissipation of 14.5 mW. It supports an external reference type and functions within a temperature range of -40°C to +125°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'GET' corresponds to the VQFN-24 package and reel packaging configuration as listed in the official Texas Instruments datasheet. Confirm RoHS compliance status and moisture sensitivity level requirements prior to procurement to ensure compatibility with assembly processes.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an 8-bit resolution and 1 MSPS sampling rate are sufficient for the application. Ensure the system requires eight single-ended inputs rather than differential configurations. Verify that the available board space accommodates the VQFN-24 footprint and that the operating temperature range meets environmental specifications.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS795x series of micro-power SAR ADCs from Texas Instruments. It shares architectural similarities with other members like the ADS7951 and ADS7953 but differs in resolution and channel count. The SRGET suffix indicates a specific tape-and-reel packaging variant suitable for automated surface-mount assembly.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements within the same family include ADS7959SDBT, which offers the same electrical specifications but utilizes a TSSOP-30 package instead of VQFN-24. Designers must verify footprint compatibility when substituting package types.
