Description

The ADAQ4380-4 is a quad channel, 16-bit precision data acquisition (DAQ) μModule® system 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. The ADAQ4380-4 is consisting of: A quad channel high resolution 16-bit, 4 MSPS simultaneous sampling SAR ADC Low noise, fully differential ADC drivers A precision 3.3V voltage reference Low noise buffer amplifiers A low noise, low dropout linear regulator, and Critical Passive components required to achieve optimum signal chain performanceUsing 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 offer the best performance from each individual blocks.ADAQ4380-4 has an on-chip oversampling blocks to improve the dynamic range and reduce noise at lower bandwidths. This block can boost up to two bits of added resolution.The ADAQ4380-4 is designed with a configurable ADC Driver stage, providing user selectable gain or attenuation settings. The ADAQ4380-4 can be operated in either fully differential or single-ended- to-differential input configurations.Housed in an 8mm x 8mm. 0.8 mm pitch, 81-ball BGA, the ADAQ4380-4 μModule® enables compact design without sacrificing performance and simplifies end system bill of materials management.The serial peripheral interface (SPI)-compatible, serial user interface is compatible with 1.8 V, 2.5 V, and 3.3 V logic controls. ADAQ4380-4 is specified to operate from −40°C to +105°C.APPLICATIONS Lab Grade Battery Test System Motor Control Current Sense Motor Control Position Feedback Sonar Power Quality Monitoring Data Acquisition System Erbium-Doped Fiber Amplifier (EDFA) applications I and Q Demodulation Table 1. μMODULE® Data Acquisition Solutions Type 250 - 500 kSPS 1 - 2 MSPS 4 MSPS 16-Bit ADAQ7988 ADAQ7980, ADAQ4001 ADAQ4380-4 (Quad Channel) 18-Bit   ADAQ4003
