GENERAL DESCRIPTION

PRODUCT HIGHLIGHTS

The AD7466/AD7467/AD7468 are 12-/10-/8-bit, high speed,

low power, successive approximation ADCs, respectively.

The parts operate from a single 1.6 V to 3.6 V power supply

and feature throughput rates up to 200 kSPS. The parts con-

tain a low noise, wide bandwidth track-and-hold amplifier that

can handle input frequencies in excess of 3 MHz.

1. Specified for supply voltages of 1.6 V to 3.6 V.

2. 12-/10-/8-Bit ADCs in a SOT-23 package.

3. High throughput rate with low power consumption. Power

consumption in normal mode of operation at 100 kSPS and

3 V is 0.9 mW max.

The conversion process and data acquisition are controlled

using CS and the serial clock, allowing the devices to interface

with microprocessors or DSPs. The input signal is sampled on

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

point. There are no pipeline delays associated with the part.

4. Flexible power/serial clock speed management.

The conversion rate is determined by the serial clock, allowing

the conversion time to be reduced through the serial clock

speed increase. Automatic power-down after conversion

allows the average power consumption to be reduced when

in power-down. Current consumption is 0.1 µA max and 8 nA

typically when in power-down.

The AD7466/AD7467/AD7468 use advanced design techniques

to achieve very low power dissipation at high throughput rates.

5. Reference derived from the power supply.

The reference for the part is taken internally from V_DD.This

allows the widest dynamic input range to the ADC. Thus, the

analog input range for the part is 0 V to V_DD. The conversion

rate is determined by the SCLK.

6. No pipeline delay. The part features a standard successive

approximation ADC with accurate control of the conversions

via a CS input.
