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

with microprocessors or DSPs. The input signal is sampled on

the falling edge of , and the conversion is also initiated at this

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 V_DD. 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

and once-off conversion control.
