1. Specified for Supply voltages of 1.8 V to 3.6 V

G E NE R AL D E S C R IP T IO N

T he AD 7466/AD 7467/AD 7468 are 12/10/8-bit, high

speed, low power, successive-approximation ADCs re-

spectively. T he parts operate from a single 1.8 V to 3.6 V

power supply and feature throughput rates up to 100

kSPS. T he parts contain a low-noise, wide bandwidth

track/hold amplifier which can handle input frequencies in

excess of 100 kHz.

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

3. H igh T hroughput with Low Power Consumption

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, which allows the average power cunsumption

to be reduced when in powerdown. Power consumption

is 0.5 µA max when in powerdown.

T he conversion process and data acquisition are controlled

using CS and the serial clock, allowing the devices to

interface with microprocessors or DSPs. T he input signal

is sampled on the falling edge of CS and the conversion is

also initiated at this point. T here are no pipelined delays

associated with the part.

5. Reference derived from the power supply.

6. N o Pipeline D elay

T he part features a standard successive-approximation

ADC with accurate control of the conversions via a CS

input.

T he AD7466/AD7467/AD7468 use advanced design tech-

niques to achieve very low power dissipation at high

throughput rates.

T he reference for the part is taken internally from V_DD.

T his allows the widest dynamic input range to the ADC.

T hus the analog input range for the part is 0 to V_DD. T he

conversion rate is determined by the SCLK.
