Product Details:

The ADAQ7767-1BBCZ μModule DAQ solution is a 24-bit precision Data acquisition (DAQ) μModule® system that integrates signal conditioning, conversion, and processing modules into a single system-level package (SiP) configuration. The ADAQ7767-1 enables rapid development of highly compact, high-performance precision DAQ systems.

The ADAQ7767-1 integrates the following features:

• Four-order, low-noise, linear phase anti-aliasing filter (AAF)

• Low noise, low distortion, high bandwidth, gain optional ADC driver, and optional linear boost buffer

• High performance medium bandwidth 24-bit sigma-δ ADC with programmable digital filter

Low noise, low pressure difference (LDO) linear regulator

• Reference buffer

• Key passive components required for the signal chain

The ADAQ7767-1 supports a variety of input types, including unipolar and bipolar single-ended, pseudo-differential and differential signals, with a maximum difference range of ±28.672 V and a common-mode voltage range of −16 V to +12 V (using IN3). With the precision of ADI's iPASSIVES™ technology, the ADAQ7767-1 has an excellent common mode rejection ratio (CMRR). Three pin-pair selectable gain Settings provide additional system dynamic range, and lower amplitude input signals improve signal-chain noise performance. In applications where high input impedance is required, the ADAQ7767-1 allows customers to choose their preferred input amplifier.
