4-channel data acquisition card ADAQ4380-4

analog16-bit

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 CSP_BGA package, the ADAQ4380-4 enables compact design without sacrificing performance and simplifies end system bill of materials management.
