ADS7952SDBTG4

Analog To Digital Converters (ADC) Overview

The ADS7952SDBTG4 is a 12-bit, 1-MSPS, 12-channel, single-ended, microPower SAR ADC with a serial interface. It operates within 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. The device features a signal-to-noise ratio (SNR) of 60 dB and a SINAD of 60 dB. Differential nonlinearity (DNL) is specified at +/- 0.5 LSB, while integral nonlinearity (INL) is +/- 0.5 LSB. It consumes 11.5 mW of power and functions across a temperature range of -40°C to +125°C. The component is housed in a TSSOP-30 package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the G4 suffix indicates lead-free compliance and RoHS adherence as per Texas Instruments standards. Confirm the specific tape-and-reel or tube packaging variant matches your assembly requirements. Ensure the ordering part number aligns exactly with the required channel count and pin configuration to avoid integration errors during procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a balance of moderate resolution and high channel count is required without excessive power draw. Compare against the ADS7950 for higher precision needs or the ADS7954 for fewer channels. Verify that the external reference voltage requirement fits within the specified input ranges and that the serial interface timing meets the system clock constraints.

Analog To Digital Converters (ADC) Part Context

This device belongs to the ADS79xx family of single-ended, microPower SAR ADCs from Texas Instruments. It shares architectural similarities with the ADS7950 and ADS7954 but offers a specific 12-channel configuration. The family is characterized by its ability to operate on low supply voltages while maintaining high throughput rates suitable for general-purpose data acquisition tasks.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS7952SBDBTG4 serves as a direct pin-compatible replacement for the ADS7952SDBTG4. Designers should verify that the package dimensions and pinout remain identical before substitution. Other family members like the ADS7950 or ADS7954 may require schematic modifications due to differing channel counts or pin assignments.
