The AD974BRSZ is a 4-channel Data Acquisition System with a serial interface. The part contains an input multiplexer, a high-speed 16-bit sampling ADC and a 2.5V reference. All of this operates from a single 5V power supply that also has a power-down mode. The interface is designed for an efficient transfer of data while requiring a low number of interconnects. It is comprehensively tested for AC parameters such as SNR and THD as well as the more traditional parameters of offset, gain and linearity. It is fabricated on Analog Devices BiCMOS process which has high performance bipolar devices along with CMOS transistors.
