ADS7825UB/1K

Analog To Digital Converters (ADC) Overview

The ADS7825UB/1K is a 16-bit, 4-channel successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates with a sampling rate of 40 kS/s and accepts single-ended inputs. The device supports both parallel and serial interfaces for data output. It functions on a single 5 V supply, with analog and digital power voltage ranges specified from 4.75 V to 5.25 V. Key performance metrics include an 83 dB signal-to-noise ratio, +/- 1 LSB differential nonlinearity, and +/- 3 LSB integral nonlinearity. Power consumption is rated at 50 mW. The component is housed in a SOIC-28 package and includes over-voltage protection features.

Analog To Digital Converters (ADC) Feature Summary

• Integrated over-voltage protection for input channels
• Flexible interface options supporting parallel and serial communication modes
• Internal reference capability alongside external reference support

Analog To Digital Converters (ADC) Applications

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix '/1K' against the manufacturer's current datasheet to confirm packaging details, as suffixes often denote tube quantities or specific reel configurations. Ensure the procurement source provides valid RoHS compliance documentation consistent with the component series specifications.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 16-bit resolution and 4-channel multiplexing capability are required within a 5 V system. Consider the SAR architecture for moderate-speed applications up to 40 kS/s. Evaluate the SOIC-28 footprint against available PCB space and verify that the parallel or serial interface aligns with the host microcontroller or DSP capabilities.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS7825 family of high-performance ADCs. It shares architectural similarities with other devices in the series but is distinguished by its 16-bit resolution and four-channel configuration. The 'UB' designation typically indicates the SOIC-28 package variant, while '/1K' specifies the tube packaging format.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS7825U is a direct functional equivalent within the same product line. Verify pin compatibility and interface requirements before substitution. Other members of the ADS78xx series may offer different resolutions or channel counts but require careful electrical parameter matching.
