Part details & applications

The ADAQ7769-1 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 ADAQ7769-1 consists of:

A low noise, low bias current, high bandwidth programmable gain amplifier (PGA) that can be programmed to operate at binary gains of 1 to 128
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 buffer
Critical passive components required for the signal chain

The ADAQ7769-1 supports a wide range of single-ended input amplitudes, with a maximum unipolar range of 0V to +24V or 0V to −24V, or a bipolar range of ±16V, basing its flexibility on the PGA supply voltages. With eight programmable binary PGA gain settings and three pin-selectable AAF gain settings, ADAQ7769-1 offers additional system dynamic range and improved signal chain noise performance with input signals of lower amplitude. The input signal is fully buffered with very low typical input bias current of 1pA. This allows easy input impedance matching and enables the ADAQ7769-1 to directly interface to sensors with high output impedance.

A fourth-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. The analog low pass filter is carefully designed to achieve high phase linearity and maximum
