ADS7822PBG4

Analog To Digital Converters (ADC) Overview

The ADS7822PBG4 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 and supports pseudo-differential or single-ended input configurations. Packaged in an SOIC-8 format, it exhibits a power consumption of 1.6 mW. Key performance metrics include a signal-to-noise and distortion ratio (SINAD) of 71 dB, with differential nonlinearity (DNL) and integral nonlinearity (INL) specified at +/- 1 LSB.

Analog To Digital Converters (ADC) Feature Summary

• MicroPower operation enabled by low-power SAR architecture
• High-speed 200 kS/s sampling capability for dynamic signals
• Flexible input handling supporting both pseudo-differential and single-ended modes

Analog To Digital Converters (ADC) Applications

• Portable battery-powered instrumentation systems
• Industrial process control data acquisition
• Medical equipment signal conditioning

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific package variant against design requirements, as the PBG4 suffix indicates an SOIC-8 package distinct from other ADS7822 family members like the UBG4. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure external reference voltage specifications align with the ADC's input range for optimal accuracy.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a balance of speed and power efficiency is required for single-channel applications. The 12-bit resolution suits general-purpose measurement tasks where 16-bit precision is unnecessary. Consider the SOIC-8 footprint constraints during PCB layout planning compared to smaller VSSOP alternatives within the same series.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS7822 family of micropower sampling ADCs from Texas Instruments. It shares core architectural similarities with variants such as the ADS7822UBG4 but differs in physical packaging. The family is designed for applications requiring moderate throughput with minimal power draw, distinguishing it from higher-resolution or multi-channel counterparts like the ADS7824.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS7822EC/2K5G4 serves as a functional alternative within the same series, offering identical electrical specifications but utilizing a VSSOP-8 package. Designers must adjust board layout dimensions to accommodate the different footprint while maintaining pin compatibility.
