ADAQ4380-4BBCZ

Overview

The ADAQ4380-4BBCZ is a quad-channel precision data acquisition μModule solution from Analog Devices. It integrates four 16-bit, 4 MSPS simultaneous sampling SAR ADCs, low-noise fully differential ADC drivers, a 3.3 V precision voltage reference, buffer amplifiers, and an LDO into a single system-in-package. The device operates on a single 5 V supply and supports input ranges of ±2 V to ±11 V with configurable gains. It features on-chip oversampling for up to 2-bit resolution boost, achieving a typical SNR of 98.3 dB at OSR ×8. The component utilizes iPassives technology for superior matching and is housed in an 8 mm × 8 mm, 81-ball CSP_BGA package.

Feature Summary

• Quad-channel 16-bit, 4 MSPS simultaneous sampling SAR ADC

• On-chip oversampling provides up to 2-bit resolution boost (SNR 98.3 dB)
• Pin-selectable input ranges: ±2 V, ±3.3 V, ±5.5 V, ±11 V
• Guaranteed 16-bit no missing codes with INL ±0.6 LSB typical

Applications

• Lab grade battery test systems
• Motor control current sense and position feedback
• Sonar and power quality monitoring
• Data acquisition systems and EDFA applications
• I and Q demodulation

Procurement Notes

Verify the BBCZ suffix against the manufacturer's ordering guide to confirm specific packaging or temperature grade variations. Ensure the design accommodates the 81-ball CSP_BGA footprint and thermal requirements. Confirm logic interface voltage compatibility (1.8 V, 2.5 V, or 3.3 V) via the VLOGIC pin. Validate that the single 5 V supply requirement aligns with the system power architecture.

Selection Notes

Select this component for multi-channel applications requiring high channel-to-channel phase matching (0.005° typical). Use when footprint reduction is critical, as it offers an 11× area reduction compared to discrete solutions. Choose if the application benefits from integrated passive components for improved drift characteristics. Ensure the input signal range fits within the selectable ±2 V to ±11 V limits without external scaling.

Part Context

The ADAQ4380-4 belongs to the µModule Data Acquisition Solutions family, which consolidates signal chain blocks to simplify design. It complements lower-speed variants like the ADAQ4370-4 (1–2 MSPS) and higher-resolution options like the ADAQ4003 (18-bit). This specific model targets high-throughput, high-precision industrial and automotive sensing where compact size and synchronized sampling are required.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Discrete alternatives would require separate ADC, amplifier, and reference selection, increasing board space and design complexity.
