Low-Power Data-Acquisition System
This chapter describes an ADC (the MAX192) that contains all major components of a data-acquisition system. Because the ADC requires very low power (1.5-mA operating and 2-μA power-down), the device can provide data acquisition for battery-powered instruments and battery management. The ADC is also well suited for robotic, portable data logging, medical instruments, and any other devices that operate from a single 5-V supply.
9.1 General Description of ADC
Figure 9-1 shows the functional block diagram of the ADC. The IC contains the elements of a 10-bit data-acquisition system that combines an eight-channel multiplexer, high-bandwidth track-and-hold, and serial interface with high conversion speed ...
