THEORY OF OPERATION The AD15252 consists of two high performance ADC channels. The dual ADC paths are independent, except for a shared internal band gap reference source, VREF. Each path consists of a differential front end amplification circuit followed by ...
Page 12
AD15252 A single channel can be powered down for moderate power savings. The powered-down channel shuts down internal circuits, but both the reference buffers and shared reference remain powered. Because the buffer and voltage reference remain powered, the wake-up time ...
