ADS7817EC/2K5

Analog To Digital Converters (ADC) Overview

The ADS7817EC/2K5 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 utilizes a 3-wire serial interface compatible with SPI. Power requirements include an analog supply voltage range of 4.75 V to 5.25 V and a digital supply voltage range of 4.75 V to 5.25 V. It consumes 2.3 mW of power and employs an external reference type. Non-linearity specifications are +/- 1 LSB for both DNL and INL, with a SINAD of 71 dB. The component is housed in a VSSOP-8 package and supports an operating temperature range from -40 C to +85 C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'EC' indicates the commercial temperature grade and '2K5' denotes the tape-and-reel quantity of 2500 units. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets before finalizing procurement orders to ensure regulatory adherence.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel, high-resolution ADC with differential inputs is required. Ensure the system design accommodates the 4.75 V to 5.25 V supply rails and provides an external voltage reference. Verify that the VSSOP-8 footprint fits the PCB layout constraints and that the 200 kS/s speed meets the application bandwidth requirements.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS7817 family of micro-power sampling ADCs. It shares architectural similarities with other devices in the series but is distinguished by its differential input stage and specific packaging options. The EC variant specifies the temperature range and manufacturing lot codes defined by Texas Instruments for commercial applications.
