ADS7817P

Analog To Digital Converters (ADC) Overview

The ADS7817P is a 12-bit successive approximation register (SAR) analog-to-digital converter (ADC) manufactured by Texas Instruments. It features a differential input architecture and operates with a sampling rate of 200 kS/s. The device requires external reference voltage and functions within an analog and digital supply voltage range of 4.75 V to 5.25 V. It utilizes a 3-wire serial interface compatible with SPI. Key performance metrics include a power consumption of 2.3 mW, a signal-to-noise and distortion ratio (SINAD) of 71 dB, differential nonlinearity (DNL) of +/- 1 LSB, and integral nonlinearity (INL) of +/- 2 LSB. The component is housed in a DIP-16 package and supports an operating temperature range from -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'P' indicates the DIP-16 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributors, as environmental declarations may vary by production batch. Ensure the source provides valid traceability for this discontinued or end-of-life component series.

Analog To Digital Converters (ADC) Selection Notes

Select the ADS7817P when a 12-bit resolution and 200 kS/s throughput are required with a through-hole mounting preference. Compare against the ADS7817U if surface-mount technology is necessary for the same electrical specifications. Verify that the external reference requirement aligns with system design constraints before finalizing the component choice.

Analog To Digital Converters (ADC) Part Context

The ADS7817 belongs to the ADS7817 family of micro-power sampling ADCs from Texas Instruments. This series is designed for applications demanding high accuracy with minimal power usage. The 'P' designation specifically identifies the plastic dual in-line package version, distinguishing it from the SOIC or VSSOP variants within the same functional family.

Analog To Digital Converters (ADC) Replacement Considerations

Publicly confirmed substitute part numbers for the ADS7817P are not available in the provided verified data. Designers should consult the official Texas Instruments datasheet for recommended pin-compatible or functionally equivalent alternatives.
