ADS7825PBG4

Analog To Digital Converters (ADC) Overview

The ADS7825PBG4 is a four-channel, 16-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates on a single 5V supply with voltage ranges of 4.75 V to 5.25 V for both analog and digital domains. The device features a sampling rate of 40 kS/s and accepts single-ended inputs. Key performance metrics include an SNR of 83 dB, SINAD of 86 dB, DNL of +/- 1 LSB, and INL of +/- 3 LSB. It supports parallel and serial interfaces, offers over-voltage protection, and consumes 50 mW of power. The component is housed in a 28-pin SOIC package and functions within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'PB' against the official datasheet to confirm package type and material compliance. Ensure the ordering part number matches the required tape-and-reel or tube packaging configuration. Confirm RoHS status and humidity sensitivity handling requirements prior to procurement to maintain component integrity during storage and assembly processes.

Analog To Digital Converters (ADC) Selection Notes

Select this component when four independent 16-bit channels are required at moderate sampling speeds. Compare against the ADS7824 if lower resolution suffices, or the ADS7828 for higher channel counts with different interface protocols. Evaluate power consumption constraints against the 50 mW dissipation rating and ensure the system architecture accommodates the specified 5V supply voltage range.

Analog To Digital Converters (ADC) Part Context

This device belongs to the ADS7825 series of CMOS sampling ADCs from Texas Instruments. It shares architectural similarities with the ADS7824 but provides increased resolution. The family is designed for applications needing multiple channels with precise conversion capabilities without requiring complex external multiplexing circuitry.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS7825P is a direct functional equivalent within the same series. Verify pin compatibility and electrical specifications before substitution. Other series members like the ADS7824 offer similar functionality with reduced resolution.
