ADS7871IDBR

ADCs/DACs - Special Purpose Overview

The ADS7871IDBR is a 14-bit Data Acquisition System (DAS) from Texas Instruments, operating at a sampling rate of 48 kSPS. It integrates an analog-to-digital converter, an 8-channel multiplexer, a programmable gain amplifier with gains ranging from 1 to 20 V/V, and an internal reference. The device utilizes a successive approximation architecture and is housed in a 28-pin SSOP package. Key electrical specifications include a maximum linear error of 0.0122% and an input voltage range extending up to 5.7 V.

ADCs/DACs - Special Purpose Feature Summary

• Integrated 14-bit ADC with 48 kSPS sampling speed
• 8-channel analog multiplexer with programmable gain amplifier (PGA)
• Internal voltage reference for simplified system design
• SSOP-28 package suitable for space-constrained applications

ADCs/DACs - Special Purpose Applications

• Industrial process control systems
• Data acquisition modules
• Battery-powered instrumentation

ADCs/DACs - Special Purpose Part Context

The ADS7871IDBR belongs to the ADS7871 family of data acquisition systems. The 'IDB' suffix indicates the industrial temperature range and SSOP package type, while 'R' denotes tape-and-reel packaging. This component consolidates multiple signal chain elements into a single IC to reduce board space and component count.

ADCs/DACs - Special Purpose Replacement Considerations

The ADS7870 is a 12-bit variant within the same family offering similar integration but lower resolution. Designers requiring higher resolution should consider the ADS7871 variants or other 14-bit DAS solutions from Texas Instruments, ensuring PGA gain ranges and sampling rates meet specific application requirements.
