Analog Devices Inc. EV-ADAQ7768-1FMC1Z

Overview

EV-ADAQ7768-1FMC1Z from Analog Devices is an evaluation board for the ADAQ7768-1, a 24-bit single-channel precision μModule data acquisition system integrating PGIA, fourth-order anti-aliasing filter, ADC driver, 24-bit Σ-Δ ADC, LDO, reference buffers, and decoupling capacitors in a 12 mm × 6 mm 84-ball CSP_BGA package. It supports ±12.6 V differential input, seven programmable gains (0.325–20.8 V/V), and three digital filters (wideband FIR, sinc5, sinc3) for applications requiring high DC accuracy and low-latency time-domain analysis.

For engineers reviewing the EV-ADAQ7768-1FMC1Z datasheet, EV-ADAQ7768-1FMC1Z pinout, EV-ADAQ7768-1FMC1Z application, or EV-ADAQ7768-1FMC1Z equivalent, this board enables rapid validation of the ADAQ7768-1's full signal chain performance-including 130 dB total system dynamic range, ±3 ppm INL, −120 dB THD at low gain, and device-to-device phase matching under 0.084° at 20 kHz-within isolated, universal-input, and predictive maintenance test setups.

Technical Context

The EV-ADAQ7768-1FMC1Z provides direct access to all ADAQ7768-1 interfaces-including SPI, MCLK (up to 16.384 MHz), REF+, REF−, GPIOs, and analog inputs-via standard 0.1" headers and SMA connectors. It implements full power sequencing, on-board LDO regulation, and configurable reference buffering (precharge or full buffer) to replicate production-level biasing conditions.

This board supports all three ADAQ7768-1 digital filter modes: wideband FIR (110 kHz BW, low ripple), sinc5 (1.024 MSPS ODR, 4 μs group delay), and sinc3 (50/60 Hz rejection, down to 50 SPS). Filter selection, gain configuration, and diagnostic enablement are controlled via SPI or pin strapping, with CRC-protected serial communication and real-time status header reporting.

FAQ

What is the primary function of the EV-ADAQ7768-1FMC1Z evaluation board?

The EV-ADAQ7768-1FMC1Z evaluation board is designed exclusively to demonstrate and validate the full performance of the ADAQ7768-1 precision μModule DAQ system. It provides complete access to all analog and digital interfaces-including differential inputs, SPI, MCLK, reference pins, and GPIOs-enabling engineers to evaluate key metrics such as 130 dB dynamic range, ±3 ppm INL, −120 dB THD, and device-to-device phase matching under real-world signal conditioning and isolation conditions. The board includes proper power sequencing, decoupling, and reference buffering to reflect production use cases.

Does the EV-ADAQ7768-1FMC1Z support isolated system integration?

Yes, the EV-ADAQ7768-1FMC1Z supports isolated system integration through its digital interface optimization for isolation. It features a 3-wire SPI interface with CRC protection and status header reporting, enabling robust communication across digital isolators. The board's layout and power domain separation align with isolated DAQ architectures, and its ADAQ7768-1 target device includes built-in diagnostics (ADC, digital, MCLK) that remain functional across isolation barriers-critical for safety-critical or high-noise industrial environments where the EV-ADAQ7768-1FMC1Z validates end-to-end signal integrity.

Can the EV-ADAQ7768-1FMC1Z be used to evaluate all three digital filter modes of the ADAQ7768-1?

Yes, the EV-ADAQ7768-1FMC1Z fully supports evaluation of all three ADAQ7768-1 digital filter modes: wideband low-ripple FIR (110 kHz bandwidth), sinc5 (1.024 MSPS output rate, 4 μs group delay), and sinc3 (50/60 Hz rejection, down to 50 SPS). Filter selection is implemented via SPI register writes or pin strapping, and the board provides accessible test points and software-configurable GPIOs to verify filter response, latency, aliasing rejection, and step response-enabling direct comparison of time-domain fidelity versus frequency-domain resolution during EV-ADAQ7768-1FMC1Z testing.

What power supply requirements must be met to operate the EV-ADAQ7768-1FMC1Z correctly?

To operate the EV-ADAQ7768-1FMC1Z correctly, users must supply 5.1–5.5 V to the IN_LDO rail (for internal LDO generation), 1.7–3.6 V to VDD_IO (digital I/O voltage), and optionally provide external 4.096 V reference (REF+) with clean grounding. The board integrates on-board LDOs for PGA, FDA, and ADC domains, eliminating need for external regulators-but strict adherence to recommended power sequencing (IN_LDO first, then VDD_IO) and low-noise decoupling (as specified in the ADAQ7768-1 datasheet) is required to achieve rated performance, especially for <1 μV RMS noise and ±3 ppm INL validation on the EV-ADAQ7768-1FMC1Z.

How does the EV-ADAQ7768-1FMC1Z facilitate sensor interfacing and gain optimization?

The EV-ADAQ7768-1FMC1Z facilitates sensor interfacing and gain optimization by providing direct access to the ADAQ7768-1's seven programmable-gain settings (0.325–20.8 V/V), fully differential analog inputs with ±12 V common-mode range and 2 pA typical input bias current, and configurable linearity boost buffer. Its SMA-connected inputs accept both grounded and floating sensors, while onboard jumpers and SPI registers allow real-time gain switching and offset calibration-enabling precise matching of sensor output amplitude to the ADAQ7768-1's ±12.6 V to ±0.197 V full-scale range without external amplification, directly validating dynamic range extension and noise floor optimization on the EV-ADAQ7768-1FMC1Z.
