AD7988-1BCPZ-RL

Overview

The AD7988-1BCPZ-RL is a 16-bit, low-power PulSAR analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It features a single-channel pseudo-differential input and operates at a throughput of 100 kSPS. The device utilizes a single 2.5 V supply with an external reference voltage ranging from 2.4 V to 5.1 V. It is housed in a 10-lead LFCSP package and supports a wide operating temperature range from -40°C to +125°C.

Feature Summary

• Zero latency architecture providing immediate data availability after conversion completion without pipeline delay.
• Versatile serial interface compatible with SPI, QSPI, MICROWIRE, and DSP protocols, supporting daisy-chaining capabilities.
• Low power dissipation optimized for battery-powered applications with independent digital logic supply options.

Applications

• Automated test equipment
• Data acquisition systems
• Medical instruments
• Machine automation

Procurement Notes

Verify the specific suffix RL against official documentation to confirm reel packaging requirements. Ensure compatibility with host system voltage levels and thermal management needs for the LFCSP package. Confirm that the 100 kSPS throughput meets application timing constraints before finalizing procurement.

Selection Notes

Select this component when a 16-bit resolution with no missing codes is required alongside low power consumption. The AD7988-1 variant is appropriate for designs needing 100 kSPS throughput rather than the higher speed AD7988-5. Consider the external reference requirement and available board space for the 10-lead LFCSP footprint.

Part Context

This part belongs to the AD7988 family of 16-bit PulSAR ADCs. It shares architectural similarities with other members like the AD7988-5 but differs in maximum sampling rate. The family is designed for precision applications requiring high linearity and low noise performance within a compact surface-mount package.

Replacement Considerations

The AD7988-5BCPZ-RL offers identical pinout and functionality but provides a higher throughput of 500 kSPS. Verify if the increased speed or power consumption aligns with design requirements before substituting.
