Analog Devices Inc. ADAQ7767-1BBCZ

Overview

ADAQ7767-1BBCZ from Analog Devices is a 24-bit precision μModule data acquisition system integrating anti-aliasing filter, gain-selectable FDA, Σ-Δ ADC, LDO, reference buffers, and decoupling capacitors in a single CSP_BGA package. It delivers 124.5 dB dynamic range, ±3.8 ppm FSR INL, 1 MSPS max output data rate (Sinc5), −118 dB THD at ±28.672 V input, and operates from −40°C to +105°C for high-accuracy industrial measurement.

For engineers reviewing the ADAQ7767-1BBCZ datasheet, ADAQ7767-1BBCZ pinout, ADAQ7767-1BBCZ application, or ADAQ7767-1BBCZ equivalent, key selection criteria include differential input range up to ±28.672 V, fourth-order analog anti-aliasing with 105 dB rejection (IN1), programmable FIR/Sinc5/Sinc3 digital filters, device-to-device phase mismatch < ±0.096° at 20 kHz, and 84-ball 0.8 mm pitch CSP_BGA packaging.

Technical Context

The ADAQ7767-1BBCZ implements a fully differential signal chain with three pin-selectable gain paths (G = 1, 0.364, 0.143) enabling ±4.096 V, ±11.264 V, or ±28.672 V differential input ranges. Its fourth-order analog anti-aliasing filter uses iPASSIVES™ technology for <0.005 dB magnitude flatness at 20 kHz and linear phase response.

Digital filtering includes wideband low-ripple FIR (256 kSPS, 110 kHz BW), Sinc5 (1024 kSPS, 4 μs group delay), and Sinc3 (50/60 Hz rejection, 60 ms settling). Configuration occurs via SPI or pin strapping, with integrated diagnostics, LDO (4.9 V output), and standby modes reducing power to <0.5 mW.

FAQ

What input voltage ranges does the ADAQ7767-1BBCZ support?

The ADAQ7767-1BBCZ supports three differential input ranges via pin-selectable gain: ±4.096 V (IN1, G = 1), ±11.264 V (IN2, G = 0.364), and ±28.672 V (IN3, G = 0.143). The wide common-mode range (−16 V to +12 V on IN3) enables direct interfacing with industrial sensors and transducers without external level-shifting circuitry. All ranges maintain 24-bit resolution and ≤±3.8 ppm INL.

How does the ADAQ7767-1BBCZ handle anti-aliasing?

The ADAQ7767-1BBCZ implements a fourth-order analog anti-aliasing filter (AAF) using Analog Devices' iPASSIVES™ thin-film resistor technology, achieving 105 dB typical rejection at the IN1 input. Combined with programmable digital filters (FIR, Sinc5, Sinc3), it ensures robust protection against out-of-band energy. The AAF provides linear phase response and <0.005 dB magnitude flatness at 20 kHz, preserving signal integrity for coherent multi-channel applications.

What digital filter options are available on the ADAQ7767-1BBCZ?

The ADAQ7767-1BBCZ offers three linear-phase FIR digital filters: wideband low-ripple FIR (256 kSPS, 110 kHz BW), Sinc5 (1024 kSPS, 4 μs group delay), and Sinc3 (50/60 Hz rejection, 60 ms settling). Each is fully programmable via SPI or pin strapping. The Sinc3 filter enables precision DC measurements in noisy AC environments, while Sinc5 supports low-latency time-domain analysis - all without compromising 24-bit resolution or dynamic range.

Does the ADAQ7767-1BBCZ include power regulation features?

Yes, the ADAQ7767-1BBCZ integrates a low-noise, low-dropout (LDO) regulator delivering 4.9 V ±1.5% at up to 20 mA, with 3 mV dropout and 350 μs start-up time. It also embeds 0.1 μF decoupling capacitors for VDD_FDA, VDD_ADC, and VDD2_ADC, eliminating six external capacitors. Power domains are independently configurable, allowing standby modes that reduce total power to <0.5 mW - ideal for battery-operated or thermally constrained systems.

What is the operating temperature range and package type of the ADAQ7767-1BBCZ?

The ADAQ7767-1BBCZ operates from −40°C to +105°C and is packaged in a 12 mm × 6 mm × 1.6 mm, 84-ball CSP_BGA with 0.8 mm ball pitch. This compact, thermally enhanced package supports high-density PCB layouts and meets industrial reliability standards. Its 8× smaller footprint versus discrete implementations simplifies thermal management and improves mechanical robustness in vibration-prone environments.
