Part details & applications

The ADAQ7768-1¹ 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 for the rapid development of highly compact, high-performance precision DAQ systems.

The ADAQ7768-1 consists of:

A low-noise, low-bias current, high-bandwidth programmable-gain instrumentation amplifier (PGIA) also capable of signal amplification and signal attenuation while maintaining high input impedance.
A fourth-order, low-noise, linear phase anti-aliasing filter.
A low-noise, low-distortion, high-bandwidth ADC driver plus an optional linearity boost buffer.
A high-performance medium bandwidth 24-bit Σ-Δ ADC with programmable digital filter.
A low-noise, low-dropout linear regulator.
Reference buffers.
Critical passive components required for the signal chain.

The ADAQ7768-1 supports fully differential input signal with a maximum range of ±12.6 V. It has an input common-mode voltage range of ±12 V with excellent common-mode rejection ratio (CMRR).

The input signal is fully buffered with very low input bias current of 2 pA typical. This allows easy input impedance matching and enables the ADAQ7768-1 to directly interface to sensors with high output impedance.

The seven pin-configurable gain settings offer additional system dynamic range and improved signal chain noise performance with input signals of lower amplitude.

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 in-ban
