ADAQ23878BBCZ

Overview

The ADAQ23878BBCZ is an 18-bit, 15 MSPS µModule data acquisition solution from Analog Devices. It integrates a low-noise fully differential ADC driver (FDA), a stable reference buffer, and a SAR ADC within a 9 mm × 9 mm CSP_BGA package. The device operates on a single 5 V supply with a specified temperature range of −40°C to +85°C. Key electrical parameters include a typical SINAD of 90.4 dB at 20 kHz, THD of −117 dB at 1 kHz, and INL error of ±3.8 ppm typical. It features a serial LVDS interface and configurable gain options ranging from 0.37 to 2.25.

Feature Summary

• Integrated system-in-package (SIP) technology combining FDA, reference buffer, and 18-bit SAR ADC
• Configurable input ranges including ±10 V, ±5 V, ±4.096 V, ±2.5 V, and ±1.5 V
• Serial LVDS digital interface supporting one-lane or two-lane output modes
• Low power consumption with dynamic scaling, dissipating 143 mW typical at 15 MSPS

Applications

• Automatic test equipment
• Data acquisition systems
• Hardware in the Loop (HiL)
• Power analyzers
• Medical imaging and instruments

Procurement Notes

Verify the specific suffix BBCZ against the manufacturer's ordering guide to confirm pinout and configuration details. Ensure that the design accommodates the humidity sensitivity classification and requires proper ESD precautions during handling due to the sensitive nature of the integrated circuit components.

Selection Notes

Select this component for applications requiring high precision and speed in a compact form factor. Consider the available gain settings (0.37 to 2.25) when designing the signal chain to match the input voltage range requirements. Evaluate the thermal resistance characteristics and PCB layout guidelines to ensure optimal performance within the specified operating temperature range.
