AD7916BCPZ-RL7

Analog To Digital Converters (ADC) Overview

The AD7916BCPZ-RL7 is a single-channel, 16-bit successive approximation register (SAR) analog-to-digital converter (ADC) from the Analog Devices PulSAR family. It operates with a sampling rate of 500 kSPS and accepts differential analog inputs. The device utilizes an external reference voltage and communicates via a 3-wire SPI-compatible serial interface. It supports an analog supply voltage range of 2.4 V to 5.1 V and a digital supply voltage of 2.5 V. Power dissipation is specified at 4.5 mW. The component is housed in a 10-lead LFCSP package and functions within an operating temperature range of -40°C to +125°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix RL7 indicates reel packaging when sourcing. Confirm the BC grade designation matches required performance specifications for temperature and accuracy. Ensure compatibility with existing PCB footprints for the LFCSP-10 package. Check for moisture sensitivity level requirements during storage and handling procedures before assembly.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a balance of 16-bit resolution and moderate speed is required. Consider the differential input requirement versus single-ended alternatives. Evaluate the external reference necessity against internal reference options in other models. Verify that the 500 kSPS rate meets system bandwidth needs without excessive power draw.

Analog To Digital Converters (ADC) Part Context

This part belongs to the AD7916 series of PulSAR ADCs. It shares architectural similarities with the AD7915 but offers a lower sampling rate of 500 kSPS compared to the 1 MSPS variant. The device is designed for applications prioritizing resolution and low power over maximum throughput speeds found in higher-speed SAR families.

Analog To Digital Converters (ADC) Replacement Considerations

The AD7915BCPZ-RL7 serves as a functional substitute with identical pinout and resolution but operates at 1 MSPS. Verify if the increased speed impacts power budget or if the lower speed of the AD7916 provides sufficient margin for the application.
