Analog Devices Inc. ADAQ7767-1 μModule DAQ Solution
Analog Devices ADAQ7767-1 μModule DAQ Solution is a 24-bit precision data acquisition (DAQ) μModule® system that combines signal conditioning, conversion, and processing blocks into a single system in package (SiP) configuration. The ADAQ7767-1 allows the rapid development of highly compact, high-performance precision DAQ systems.
The ADAQ7767-1 incorporates 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 Σ-Δ ADC with a programmable digital filter
• A low noise, low dropout (LDO) linear regulator
• Reference buffers
• Critical passive components required for the signal chain
The ADAQ7767-1 offers an operating temperature range of -40°C to +105°C and is engineered in a 12mm x 6mm, 84-ball CSP_BGA package with 0.8mm ball pitch, making it ideal for multiple-channel applications. The footprint of the ADAQ7767-1 is eight times smaller than the footprint of the same solution employing discrete components.
