ADS7852YB/250

Analog To Digital Converters (ADC) Overview

The ADS7852YB/250 is a 12-bit, 8-channel analog-to-digital converter (ADC) manufactured by Texas Instruments. It utilizes successive approximation register (SAR) architecture and supports single-ended inputs with a parallel output interface. The device operates on a single supply voltage ranging from 4.75 V to 5.25 V for both analog and digital domains. It achieves a sampling rate of 500 kS/s with a signal-to-noise ratio (SNR) of 72 dB. Differential nonlinearity (DNL) and integral nonlinearity (INL) are specified at +/- 1 LSB. The component includes an internal reference and is housed in a TQFP-32 package, operating within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix code against the manufacturer's current documentation to confirm pinout compatibility and electrical specifications. Check for end-of-life status or obsolescence notices prior to finalizing procurement plans. Ensure that the ordering part number matches the required package type and temperature grade. Confirm RoHS compliance details if restricted substances are a constraint for the target application.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a balance of moderate speed and high channel count is required without external reference components. Compare performance metrics such as SNR and linearity against alternative SAR ADCs in the same family. Consider the parallel interface requirements for the host microcontroller or DSP. Evaluate power dissipation limits relative to the thermal constraints of the TQFP-32 package in the final enclosure design.
