ADS7865IPBSR

Analog To Digital Converters (ADC) Overview

The ADS7865IPBSR is a dual-channel, 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates within an analog and digital supply voltage range of 2.7 V to 5.5 V. The device supports simultaneous sampling at a rate of 2 MS/s with differential or pseudo-differential input types. Key performance metrics include a signal-to-noise ratio of 71.7 dB, integral nonlinearity of +/- 1.25 LSB, and differential nonlinearity of +/- 1 LSB. Power consumption is specified at 30 mW typical and 44 mW maximum. It features an internal reference and is housed in a 32-lead TQFP package.

Analog To Digital Converters (ADC) Feature Summary

• Simultaneous sampling architecture for synchronized multi-channel acquisition
• Integrated internal voltage reference to reduce external component count
• High-speed parallel interface for efficient data transfer

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring high-speed data acquisition
• Medical instrumentation utilizing multi-channel signal processing
• Vibration monitoring and acoustic analysis equipment

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IPBSR corresponds to the tape and reel packaging configuration required for automated assembly processes. Confirm that the operating temperature range of -40°C to +125°C aligns with the environmental specifications of the target application. Ensure compatibility with the system's parallel interface logic levels and timing requirements before integration.

Analog To Digital Converters (ADC) Selection Notes

Select this component when simultaneous sampling of two channels is critical, as opposed to multiplexed alternatives which introduce aperture delay errors. The 12-bit resolution and 2 MSPS speed offer a balance between precision and throughput suitable for general-purpose high-speed applications. Consider the power dissipation limits and thermal management requirements associated with the TQFP-32 package during PCB layout.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS7865 family of dual-channel ADCs from Texas Instruments. It shares the same core functionality and pinout with the ADS7865IPBS, differing primarily in the shipping packaging format. The IPBSR variant utilizes a reel-based packaging solution designed for surface-mount technology (SMT) pick-and-place manufacturing lines.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS7865IPBS serves as the tray-packaged equivalent with identical electrical characteristics. Designers may also evaluate other members of the ADS786x family if channel count or resolution requirements differ, provided the interface and form factor remain compatible.
