ADS7852Y/250G4

Analog To Digital Converters (ADC) Overview

The ADS7852Y/250G4 is a 12-bit analog-to-digital converter (ADC) from Texas Instruments, featuring an 8-channel single-ended input configuration. It utilizes a Successive Approximation Register (SAR) architecture to achieve a sampling rate of 500 kS/s. The device provides parallel digital output and operates on a single 5V supply, with both analog and digital voltage ranges specified between 4.75 V and 5.25 V. Key performance metrics include a Signal-to-Noise Ratio (SNR) of 72 dB, Differential Nonlinearity (DNL) of +/- 1 LSB, and Integral Nonlinearity (INL) of +/- 2 LSB. It is housed in a 32-pin TQFP package and supports an operating temperature range from -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrates an internal reference voltage source to simplify system design.
• Offers high-speed data conversion with a 500 kS/s sampling rate per channel.
• Features low power consumption suitable for battery-operated applications.

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring multi-channel signal acquisition.
• Data acquisition systems for monitoring multiple sensor inputs.
• Medical instrumentation devices needing precise analog signal digitization.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix G4 indicates RoHS compliance and lead-free status as per manufacturer documentation. Confirm current availability status, as lifecycle notices may indicate end-of-life or obsolescence phases for this component. Ensure the TQFP-32 package type matches your PCB footprint requirements before ordering.

Analog To Digital Converters (ADC) Selection Notes

Select this model when eight single-ended channels are required with parallel interface compatibility. Consider the ADS7852YB/2K variant if external reference capability or improved INL specifications are necessary. Evaluate the ADS7862 series if differential inputs or SPI interface are preferred over parallel outputs.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADS7852 family of high-speed, low-power ADCs. The 'G4' suffix typically denotes Green/RoHS-compliant packaging. It serves as a bridge between analog sensor signals and digital processing units in environments requiring moderate resolution and speed.

Analog To Digital Converters (ADC) Replacement Considerations

ADS7852YB/2K: Offers similar specs but with external reference capability and potentially different INL values. ADS7852Y/250: Standard version without the G4 suffix, functionally equivalent regarding electrical parameters.
