ADAQ4001BBCZ

Overview

The ADAQ4001BBCZ is a 16-bit, 2 MSPS µModule data acquisition solution by Analog Devices. It integrates a SAR ADC, fully differential driver, and reference buffer in a 7 mm × 7 mm CSP_BGA package. Key specifications include ±4.6 ppm typical INL, 95.6 dB typical SINAD at G = 0.454, and 51.6 mW total power dissipation. The device supports SPI/QSPI/MICROWIRE/DSP interfaces with versatile logic supply options from 1.8 V to 5 V.

Feature Summary

• System-in-package (SIP) integration of ADC, FDA, and reference buffer
• iPassives matched resistor array for superior matching and drift characteristics
• Selectable input ranges: ±10 V, ±5 V, or ±2.5 V with 5 V VREF
• Low power consumption: 51.6 mW typical at 2 MSPS

Applications

• Automatic test equipment
• Machine automation
• Process controls
• Medical instrumentation
• Digital control loops

Procurement Notes

Verify the specific suffix BBCZ corresponds to the 49-ball CSP_BGA package configuration. Confirm that the ordering suffix does not alter the functional parameters defined in the Rev B datasheet. Ensure compatibility with the required thermal management guidelines for the BC-49-5 package type during procurement planning.

Selection Notes

Select this component when high channel density and reduced bill of materials are required. The integrated iPassives minimize temperature-dependent errors. Verify that the host interface voltage (VIO) matches the available logic levels, as the device supports 1.8 V, 2.5 V, 3 V, or 5 V. Ensure the application can accommodate the 7 mm × 7 mm footprint.

Part Context

The ADAQ4001 belongs to the µModule Data Acquisition Solutions family, which includes the ADAQ7988, ADAQ7980, and ADAQ4003. It is designed to simplify precision measurement system development by transferring signal chain design challenges from the user to the device. It serves as a compact alternative to discrete signal chain designs.

Replacement Considerations

The ADAQ4003 is an 18-bit variant within the same family offering similar integration but higher resolution. For lower throughput requirements, the ADAQ7988 provides a 16-bit option at 500 kSPS. Direct pin-to-pin replacement is not guaranteed due to package and performance differences; verify electrical compatibility before substitution.
