ADS7822UB/2K5

Analog To Digital Converters (ADC) Overview

The ADS7822UB/2K5 is a 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates with an analog supply voltage range of 2.7 V to 5.25 V and features a sampling rate of 200 kS/s. The device utilizes a 3-wire serial interface for data communication. It is housed in an SOIC-8 surface-mount package. Key performance metrics include a differential nonlinearity (DNL) and integral nonlinearity (INL) of +/- 1 LSB, and a signal-to-noise and distortion ratio (SINAD) of 71 dB. The component consumes 1.6 mW of power and functions within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Micro-power consumption capability suitable for battery-operated applications
• High-speed 200 kS/s sampling rate with 12-bit resolution
• Flexible input configuration supporting pseudo-differential or single-ended signals

Analog To Digital Converters (ADC) Applications

• Portable instrumentation systems requiring low power consumption
• Industrial process control data acquisition
• Battery-powered measurement devices

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix /2K5 indicates tape-and-reel packaging containing 2500 units per reel. Confirm the UB variant corresponds to the SOIC-8 package type rather than the VSSOP-8 used in other family members. Ensure compatibility with external reference voltage requirements as specified in the official datasheet.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 200 kS/s sampling rate is required alongside micro-power operation. Compare against the ADS7822EC series if a smaller VSSOP-8 package is preferred, noting that the EC version may offer improved linearity specifications. Verify that the digital supply voltage requirements align with the system logic levels.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS7822 family of high-speed, micro-power ADCs from Texas Instruments. The family includes variants such as the ADS7822EB and ADS7822EC, which share similar electrical characteristics but differ in package types like MSOP-8 or VSSOP-8. The ADS7822UB specifically denotes the SOIC-8 package configuration.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS7822EC/2K5 serves as a pin-compatible alternative within the same family, offering identical functionality in a VSSOP-8 package. Other family members like the ADS7822EB provide similar performance in different form factors.
