ADS7852Y/2K

Analog To Digital Converters (ADC) Overview

The ADS7852Y/2K is a 12-bit successive approximation register (SAR) analog-to-digital converter featuring eight single-ended input channels and parallel data output. It operates with a sampling rate of 500 kS/s and supports both internal and external reference configurations. The device functions on a single 4.75 V to 5.25 V supply for both analog and digital domains, consuming 13 mW of power. Key performance metrics include a signal-to-noise ratio of 72 dB, differential nonlinearity of +/- 1 LSB, and integral nonlinearity of +/- 1 LSB. It is housed in a TQFP-32 package and rated for operation between -40°C and +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Eight-channel multiplexed input architecture supporting single-ended signals
• Integrated internal voltage reference option alongside external reference capability
• High-speed parallel interface enabling direct connection to microprocessors or DSPs
• Low-power SAR architecture optimized for battery-operated applications

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring multi-channel data acquisition
• Portable instrumentation and test equipment
• Medical monitoring devices needing low-power ADC solutions
• Automotive sensor interfaces

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix '2K' indicates reel packaging when sourcing. Confirm RoHS compliance status through official documentation as specifications may vary by production batch. Check current lifecycle status as older TI components may be subject to obsolescence notices. Ensure ESD handling protocols are followed during assembly due to moisture sensitivity classification.

Analog To Digital Converters (ADC) Selection Notes

Select this component when eight single-ended inputs are required without simultaneous sampling needs. Compare against the ADS7862 series if differential inputs or simultaneous sampling capabilities are necessary instead. Consider the ADS7852Y/250 variant if cut-tape packaging is preferred over reel quantities. Evaluate power consumption requirements against the 13 mW typical dissipation at full speed.

Analog To Digital Converters (ADC) Part Context

This part belongs to the Texas Instruments ADS7852 family of high-speed, low-power ADCs. It shares architectural similarities with other members like the ADS7851 but differs in channel count and input configuration. The YB package designation typically refers to the TQFP-32 form factor used across this product line for surface-mount integration.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS7852Y/250 serves as a functional equivalent with identical electrical characteristics but differs in tape-and-reel quantity packaging. No direct cross-brand replacements are documented in public sources; design-in requires careful interface timing verification.
