AD72731  
AD72741  
AD7276  
The AD7273/AD7274 are 10-/12-bit, high speed, low power,  
successive approximation 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. Each part contains a low  
noise, wide bandwidth track-and-hold amplifier that can handle  
input frequencies in excess of 55 MHz.

using  
and the serial clock, allowing the devices to interface  
CS  
with microprocessors or DSPs. The input signal is sampled on  
the falling edge of , and the conversion is also initiated at this  
CS  
point. The conversion rate is determined by the SCLK. There  
are no pipeline delays associated with these parts.  
PRODUCT HIGHLIGHTS  
1. 3 MSPS ADCs in an 8-lead TSOT package.  
2. High throughput with low power consumption.  
3. Flexible power/serial clock speed management.  
The AD7273/AD7274 use advanced design techniques to  
achieve very low power dissipation at high throughput rates.  
Allows maximum power efficiency at low throughput rates.  
4. Reference can be driven up to the power supply.  
5. No pipeline delay.  
The reference for the parts is applied externally and can be in  
the range of 1.4 V to VDD. This allows the widest dynamic input  
range to the ADC.  
6. The parts feature a standard successive approximation ADC  
with accurate control of the sampling instant via a  
input  
CS  
and once-off conversion control.
