The ADAQ4001 is a μModule® precision data acquisition (DAQ), signal chain solution that reduces the development cycle of a precision measurement system by transferring the signal chain design challenge of component selection, optimization, and layout from the designer to the device.
Using system-in-package (SIP) technology, the ADAQ4001 reduces end system component count by combining multiple common signal processing and conditioning blocks into a single device. These blocks include a high resolution 16-bit, 2 MSPS successive approximation register (SAR), analog-to-digital converter (ADC), a low noise, fully differential ADC driver amplifier (FDA), and a stable reference buffer.
Using Analog Devices, Inc., iPassives® technology, the ADAQ4001 also incorporates crucial passive components with superior matching and drift characteristics to minimize temperature dependent error sources and to offer optimized performance (see Figure 1 in the data sheet). Housing this signal chain solution in a small, 7 mm × 7 mm, 0.80 mm pitch, 49-ball CSP_BGA enables compact form factor designs without sacrificing performance and simplifies end system bill of materials management. This level of system integration makes the ADAQ4001 much less sensitive to printed circuit board (PCB) layout while still providing flexibility to adapt to a wide range of signal levels.
The serial peripheral interface (SPI)-compatible, serial user interface is compatible with 1.8 V, 2.5 V, 3 V, or 5 V logic, using a separate VIO supply. Specified operation of the ADAQ4001 is from −40°C to +125°C.

Evaluation Kits (1)
The ADAQ4001 and ADAQ4003 µModule® data acquisition system evaluation kit (EVAL-ADAQ4001FMCZ or EVAL-ADAQ4003FMCZ) contains the EVAL-ADAQ4001PMDZ or EVAL-ADAQ4003PMDZ peripheral module (Pmod) board and the EVAL-PMD-IB1Z Pmod to field programmable grid array (FPGA) mezzanine card (FMC) interposer board that interfaces with the system demonstration controller board (EVAL-SDP-CH1Z) via a 160-pin FMC connector, as shown in Figure 1. in the user guide.
The ADAQ4001 µModule and ADAQ4003 µModule combine multi-ple common signal processing and conditioning blocks into a single device that includes a low noise, fully differential analog-to-digital converter (ADC) driver, a stable reference buffer, a high resolution, 16-bit or 18-bit, 2 MSPS successive approximation register (SAR) ADC, and the critical passive components necessary for optimum performance.
The EVAL-ADAQ4001PMDZ and EVAL-ADAQ4003PMDZ on-board components include the following:
- The ADR4550 high precision, buffered band gap, 5.0 V voltage reference (see Figure 25 in user guide)
- An optional ADA4898-1 high voltage, low noise, low distortion, unity-gain stable, high speed op amp (see Figure 26 in user guide)
- An optional AD8251 programmable gain in-amp (see Figure 26 in user guide)
