GENERAL DESCRIPTION  
Table 1.  
Part Number  
The AD7276/AD7277/AD7278 are 12-/10-/8-bit, high speed,  
low power, successive approximation analog-to-digital converters  
(ADCs), respectively. The parts operate from a single 2.35 V  
to 3.6 V power supply and feature throughput rates of up to  
3 MSPS. The parts contain a low noise, wide bandwidth track-  
and-hold amplifier that can handle input frequencies in excess  
of 55 MHz.

3. High throughput with low power consumption.  
4. Flexible power/serial clock speed management. This allows  
maximum power efficiency at low throughput rates.  
5. Reference derived from the power supply.  
6. No pipeline delay. The parts feature a standard successive  
approximation ADC with accurate control of the sampling  
The AD7276/AD7277/AD7278 use advanced design techniques  
to achieve very low power dissipation at high throughput rates.  
The reference for the part is taken internally from VDD. This  
allows the widest dynamic input range to the ADC; therefore,  
the analog input range for the part is 0 to VDD. The conversion  
rate is determined by the SCLK.
