1. Describe

The AD7276BRMZ/AD7277/AD7278 are 12-bit/10-bit/8-bit, high speed, Low Power, Successive Approximation Analog-to-Digital Converter (ADC), respectively. These parts operate from a single 2.35 V supply to 3.6 V supply and up to functional throughput 3 milliseconds. These parts contain a low noise, wide bandwidth track-and-hold amplifier that can handle excessive input frequencies 55 MHz. Controlled conversion process and data acquisition Using CS and Serial Clock, Allows Device Interface with microprocessor or DSP. The input signal is sampled the falling edge of CS, and a conversion is initiated on this View. There is no pipeline delay associated with this part. The AD7276BRMZ/AD7277/AD7278 utilize advanced design techniques Very low power consumption is achieved at high throughput rates. The part's reference is taken internally from VDD. this allows the widest dynamic input range of the ADC; therefore, The device has an analog input range of 0 to VDD. convert The rate is determined by SCLK.
