Part details & applications

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 the following:

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 (LDO) 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 ±28.672 V and a common-mode voltage range of −16 V to +12 V using IN3. With the precision of Analog Devices iPASSIVES™ technology, the 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, the ADAQ7767-1 allows the customer to choose their preferred input amplifier.

A fourth-order low-pass analog filter combined with the user-programmable digital filter ensures that the signal chain is protected against the high frequency noise and out of band tones presented at the input node from aliasing back into the band of interest. The analog low pass filter is carefully designed to achieve high phase linearity and maximum in-band magnitude response flatness. Constructed with iPASSIVES techn
