ADAQ7768-1BBCZ

Overview

The ADAQ7768-1BBCZ is a 24-bit single-channel precision data acquisition μModule system encapsulating signal conditioning, conversion, and processing in an 84-ball CSP_BGA package. It integrates a programmable-gain instrumentation amplifier (PGIA), fourth-order anti-aliasing filter, ADC driver, and 256 kSPS Σ-Δ ADC. Key electrical parameters include ±12.6 V differential input range, 2 pA typical input bias current, ±3 ppm typical INL, and up to 130 dB total dynamic range. The device supports seven gain settings from 0.325 V/V to 20.8 V/V and operates within −40°C to +105°C.

Feature Summary

• Integrated 24-bit Σ-Δ ADC with throughput rates up to 256 kSPS and optional Sinc5 mode up to 1.024 MSPS
• Seven pin-configurable gain options ranging from 0.325 V/V to 20.8 V/V for flexible input scaling
• Fourth-order analog anti-aliasing filter with linear phase response and >100 dB alias rejection
• Ultra-low input bias current of 2 pA typical, enabling direct connection to high-impedance sensors

Applications

• Universal input measurement platforms
• Electrical test and measurement equipment
• Sound, vibration, and acoustic research systems
• Hardware-in-the-loop verification setups
• Predictive maintenance condition monitoring

Procurement Notes

Verify the specific suffix BBCZ against the manufacturer's ordering guide to confirm the exact temperature grade and packaging variant. Confirm that the required supply voltages align with the integrated LDO specifications and external power requirements. Ensure the design accommodates the 84-ball BGA footprint dimensions and thermal dissipation needs.

Selection Notes

Select this component when a compact, high-performance DAQ solution is required without discrete component complexity. Choose based on the necessary input voltage range and gain settings; higher gains provide better resolution for low-level signals but reduce the full-scale input range. Consider the digital filter requirements, such as the need for wideband FIR analysis versus low-latency Sinc5 capture or DC-focused Sinc3 filtering.

Part Context

The ADAQ7768-1 is the single-channel version of the AD7768, which is an eight-channel simultaneous sampling ADC. While the AD7768 focuses on multi-channel synchronization, the ADAQ7768-1 provides a reusable, highly integrated platform optimized for precision AC and DC measurements in isolated and non-isolated applications.

Replacement Considerations

The AD7768 serves as the multi-channel counterpart within the same family. For discrete implementations, no direct single-package replacement exists due to the μModule integration. Verify compatibility if migrating from older ADI DAQ modules like the ADAQ4224.
