GENERAL DESCRIPTION

PRODUCT HIGHLIGHTS

The AD7466/AD7467/AD7468¹are 12-/10-/8-bit, high speed,

low power, successive approximation analog-to-digital

converters (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 with low power dissipation. The parts contain a low

noise, wide bandwidth track-and-hold amplifier, which 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-, and 8-bit ADCs in SOT-23 and MSOP packages.

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 maximum.

4. Flexible power/serial clock speed management.

The conversion rate is determined by the serial clock,

allowing the conversion time to be reduced through

increases in the serial clock speed. Automatic power-down

after conversion allows the average power consumption to

be reduced when in power-down. Current consumption is

0.1 μA maximum and 8 nA typically when in power-down.

The conversion process and data acquisition are controlled

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. There are no pipeline delays associated with the part.

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.

5. Reference derived from the power supply.

6. No pipeline delay.

7. The part features a standard successive approximation

ADC with accurate control of conversions via a

input.
