Using system-in-package (SIP) technology, the ADAQ4380-4 reduces end system ponent count by bining multiple mon signal processing and conditioning blocks into a single device. These blocks include a quad-channel, high resolution 16-bit, 4 MSPS simultaneous sampling SAR ADC, low noise, fully differential ADC driver amplifier, a 3.3 V precision voltage reference, low...
