Data acquisition card ADAQ7767-1

The ADAQ7767-1 is a 24-bit precision data acquisition (DAQ) μModule® system that encapsulates signal conditioning, conversion, and processing blocks into one system in package (SiP) design that enables rapid development of highly compact, high performance precision DAQ systems. The ADAQ7767-1 consists of: A fourth order, low noise, linear phase anti-aliasing filter (AAF) A low noise, low distortion, high bandwidth, gain-selectable ADC driver plus an optional linearity boost buffer A high-performance medium bandwidth 24-bit sigma delta ADC with programmable digital filter A low noise, low dropout linear regulator Reference buffers Critical passive components required for the signal chain The ADAQ7767-1 supports a wide variety of input types, which include unipolar and bipolar single-ended, pseudo-differential and differential signals, with a maximum differential range of ±28V and a common mode voltage range of −16V to +12V using IN3. With the precision of Analog Devices’s iPASSIVES™ technology, ADAQ7767-1 performs with excellent common mode rejection ratio (CMRR). The three pairs of pin-selectable gain settings offer additional system dynamic range and improved signal chain noise performance with input signals of lower amplitude. In applications requiring high input impedance, ADAQ7767-1 allows the customer to choose their preferred input amplifier. A 4th order low-pass analog filter combined with the user programmable digital filter ensures the signal chain is fully protected against the high frequency noise and out of band tones presented at the input node from aliasing back into the band of interest.
