ADS7887SDCKR

Analog To Digital Converters (ADC) Overview

The Texas Instruments ADS7887SDCKR is a single-channel, 10-bit successive approximation register (SAR) analog-to-digital converter. It operates within an analog and digital supply voltage range of 2.35 V to 5.25 V. The device supports a maximum sampling rate of 1.25 MSPS with a serial interface. Key performance metrics include a signal-to-noise ratio of 61 dB, differential nonlinearity of ±0.5 LSB, and integral nonlinearity of ±0.75 LSB. Power consumption is specified at 3.8 mW, with a maximum power dissipation of 7.5 mW. It functions in temperatures from -40°C to +125°C and is housed in a SC-70-6 surface-mount package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'R' indicates tape-and-reel packaging when ordering. Confirm that the component meets RoHS compliance standards required by your region. Ensure the SC-70-6 footprint matches your PCB layout constraints. Check moisture sensitivity levels for proper storage and reflow soldering profiles. Validate that the operating temperature range aligns with your system's environmental requirements.

Analog To Digital Converters (ADC) Selection Notes

Select this model for applications requiring 10-bit resolution at speeds up to 1.25 MSPS. Consider the ADS7887 family if lower resolution or different pinout configurations are needed. Evaluate the 2.35 V minimum supply voltage against your system's power rails. Compare the 61 dB SNR against your signal integrity requirements. Verify compatibility with your microcontroller's serial communication interface.

Analog To Digital Converters (ADC) Part Context

The ADS7887 belongs to the TI ADS788x family of high-speed, serial interface ADCs. This family includes variants such as the ADS7886 (12-bit) and ADS7888 (8-bit). All members share similar low-power characteristics and compact packaging options. The ADS7887 specifically targets the mid-resolution segment of this series.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS7887SDC is the non-tape-and-reel equivalent of this part number. Other family members like the ADS7886 or ADS7888 offer different resolutions but may require software adjustments.
