The ADAQ4380-4 is a quad-channel precision data acquisition (DAQ) signal chain μModule solution that reduces the development cycle of a precision measurement system by transferring the signal chain design challenges of component selection, optimization, and layout from the designer to the device. Using system-in-package (SIP) technology, the ADAQ4380-4 reduces end system component count by combining multiple common signal processing and conditioning blocks into a single device. These blocks include a quad-channel, high resolution 16-bit, 4 MSPS simultaneous sampling SAR ADC, low noise, fully differential ADC driver amplifier, a 3.3 V precision voltage reference, low-noise buffer amplifiers, and low-dropout linear regulator. The ADAQ4380-4 has an on-chip oversampling blocks to improve the dynamic range and reduce noise at lower bandwidths. The oversampling can boost up to two bits of added resolution. It provides the flexibility of a configurable ADC driver feedback loop to allow four gain and attenuation adjustments, and accept both fully differential or single-ended to differential input configuration. Using Analog Devices, Inc. iPassives® technology, the ADAQ4380-4 incorporates critical passive components with superior matching and drift characteristics to minimize temperature dependent error sources and to offer optimized signal chain performance. Housed in a small 8 mm × 8 mm × 0.8 mm pitch, 81- ball CSPBGA package, the ADAQ4380-4 enables compact design without sacrificing performance and simplifies end system bill of materials management. The ADAQ4380-4's optimum performance is guaranteed with a single 5 V supply operation, all the required bypass and decoupling capacitors are included inside the package. The level of ADAQ4380-4 system integration solves many design challenges, which enables a compact and simple solution for a multichannel application. The conversion result can clock out simultaneously through 4-wire mode for faster throughput or through 1-wire serial mode when slower throughput is allowed. The ADAQ4380-4 is compatible with 1.8 V, 2.5 V, and 3.3 V interfaces using the separate logic supply. The ADAQ4380-4 is specified to operate over a temperature range of −40°C to +105°C.
