ADS7954SDBT

Analog To Digital Converters (ADC) Overview

The ADS7954SDBT is a 10-bit, 1-MSPS, 4-channel single-ended microPower SAR ADC from Texas Instruments. It 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. The device features a serial SPI-compatible interface and is housed in a 30-pin TSSOP package. Key performance metrics include a Signal-to-Noise Ratio (SNR) of 60 dB and a SINAD of 60 dB. Differential Nonlinearity (DNL) and Integral Nonlinearity (INL) are specified at +/- 0.5 LSB. The component consumes 11.5 mW of power and functions within a temperature range of -40°C to +125°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix to confirm the tube packaging format, as indicated by the 'T' designation. Ensure compatibility with external reference voltages near 2.51 V for optimal linearity performance. Confirm moisture sensitivity level handling requirements during assembly to maintain device reliability under specified operating conditions.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a balance of moderate resolution and high sampling speed is required for single-ended signals. Compare against the ADS7950 for higher 12-bit resolution or the ADS7955 for increased channel count. Consider the external reference requirement if internal references are preferred in alternative models.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS795x family of microPower SAR ADCs, designed for applications requiring multiple channels with moderate precision. It shares architectural similarities with other members like the ADS7950 and ADS7955, differing primarily in resolution and channel count while maintaining consistent power and interface characteristics.

Analog To Digital Converters (ADC) Replacement Considerations

ADS7950SDBT offers 12-bit resolution with identical channel count and package. ADS7955SDBT provides 8 channels with 10-bit resolution in the same package. Verify pinout compatibility and software register settings when substituting within the ADS795x series.
