Overview
The AD7693BRMZRL7 is a 16-bit, successive approximation analog-to-digital converter (ADC) produced by Analog Devices Inc. This device operates from a single power supply, VDD, and features a low power, high speed ADC with no missing codes. It includes an internal conversion clock and a versatile SPI-compatible serial interface port. The ADC samples the voltage difference between the IN+ and IN− pins, with the voltages on these pins swinging in opposite phase between 0 V and VREF about VREF/2. The power consumption of the AD7693 scales linearly with throughput, making it efficient for various applications.
