ADAQ7767-1BBCZ

Analog To Digital Converters (ADC) Overview

The ADAQ7767-1BBCZ is a 24-bit precision data acquisition μModule system encapsulating signal conditioning, conversion, and processing blocks into one system in package (SiP) design. It features a fourth-order anti-aliasing filter, gain-selectable ADC driver, and a high-performance medium bandwidth 24-bit Σ-Δ ADC with programmable digital filters. The device supports three pin-selectable gain options: 1 (IN1), 0.364 (IN2), or 0.143 (IN3). Maximum input range reaches ±28.672 V differential on IN3, with a wide common-mode voltage range of −16 V to +12 V. Total system dynamic range is up to 124.5 dB, with typical THD of −118 dB at the maximum input range. Operating temperature spans from −40°C to +105°C.

Ensure all electrical parameters align with your system specifications. Check for any recent revisions to the datasheet that may affect compatibility. Validate component authenticity through authorized distribution channels.

Analog To Digital Converters (ADC) Selection Notes

Evaluate the required input voltage range and select the appropriate gain setting (IN1, IN2, or IN3) to optimize dynamic range. Consider the necessary output data rate and choose between the wideband FIR, Sinc5, or Sinc3 digital filters based on latency and rejection needs. Verify power supply constraints and ensure the internal LDO meets the load requirements. Assess thermal management capabilities within the target operating temperature range.

Analog To Digital Converters (ADC) Part Context

This component belongs to Analog Devices' μModule DAQ family, designed to replace discrete signal chains. It integrates critical passive components using iPASSIVES technology for superior resistance matching. The device reduces board space significantly compared to discrete solutions while maintaining high precision and phase matching across multiple units.

Analog To Digital Converters (ADC) Replacement Considerations

No direct public substitute part numbers are confirmed for this specific model. Discrete alternatives would require redesigning the entire signal chain including the PGA, anti-aliasing filter, and ADC interface.
