ADAQ7988BCCZ

Analog To Digital Converters (ADC) Overview

The ADAQ7988BCCZ is a 16-bit, 500 kSPS μModule data acquisition system from Analog Devices. It integrates a SAR ADC, high-bandwidth driver, reference buffer, and power management into a 24-lead LGA package. Key specifications include ±8 ppm typical INL, 91.5 dB SNR at 10 kHz, and 16.5 mW typical power dissipation at 500 kSPS. The device supports dual or single-supply configurations with VDD ranging from 3.5 V to 10 V and VIO from 1.7 V to 5.5 V. It features an SPI-compatible serial interface with daisy-chain capability and operates across a temperature range of −55°C to +125°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrates critical signal chain components including a 16-bit SAR ADC, ADC driver, reference buffer, and power management block within a single SiP design.
• Provides flexible supply configuration supporting 1.8 V, 2.5 V, 3 V, or 5 V logic interfaces via the VIO pin.
• Features a SPI-/QSPI-/MICROWIRE™-/DSP-compatible serial interface that allows multiple devices to be daisy-chained on a single bus.
• Includes configurable ADC driver feedback loop to enable gain and common-mode adjustments for versatile application support.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure correct packaging and tape-and-reel specifications. Confirm that the component meets RoHS compliance requirements for your region. Check for any recent revision changes in the technical documentation that might affect pin compatibility or electrical characteristics before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select the ADAQ7988BCCZ when a 500 kSPS sampling rate is sufficient, as opposed to the 1 MSPS ADAQ7980. Ensure the application requires the integrated driver and reference buffer to simplify PCB layout. Verify that the required input voltage range and supply voltages align with the device's specified operating conditions. Consider the thermal resistance values if operating at maximum throughput in enclosed environments.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADAQ7980/ADAQ7988 family of μModule data acquisition systems. It shares the same package footprint and functional architecture as the ADAQ7980 but offers a lower maximum sampling rate of 500 kSPS compared to the ADAQ7980's 1 MSPS. Both devices integrate similar signal conditioning blocks to reduce design complexity.

Analog To Digital Converters (ADC) Replacement Considerations

The ADAQ7980 is a functionally compatible alternative within the same family, offering higher throughput at 1 MSPS while maintaining identical pinouts and integration levels. No other direct cross-model replacements are documented in the provided source material.
