GENERAL DESCRIPTION
The AD72661 is a dual, 12-bit, high speed, low power, successive
approximation ADC that operates from a single 2.7 V to 5.25 V
power supply and features throughput rates up to 2 MSPS. The
device contains two ADCs, each preceded by a 3-channel
multiplexer, and a low noise, wide bandwidth track-and-hold
amplifier that can handle input frequencies in excess of 30 MHz.
The conversion process and data acquisition use standard
control inputs allowing easy interfacing to microprocessors or
DSPs. The input signal is sampled on the falling edge of CS;
conversion is also initiated at this point. The conversion time is
determined by the SCLK frequency. There are no pipelined
delays associated with the part.
The AD7266 uses advanced design techniques to achieve very
low power dissipation at high throughput rates. With 5 V
supplies and a 2 MSPS throughput rate, the part consumes
6.2 mA maximum. The part also offers flexible power/
throughput rate management when operating in normal mode
as the quiescent current consumption is so low.
The analog input range for the part can be selected to be a 0 V
to VREF (or 2 × VREF) range, with either straight binary or twos
complement output coding. The AD7266 has an on-chip 2.5 V
reference that can be overdriven when an external reference is
preferred. This external reference range is 100 mV to VDD.

PRODUCT HIGHLIGHTS
1.
Two Complete ADC Functions Allow Simultaneous
Sampling and Conversion of Two Channels.
Each ADC has three fully/pseudo differential pairs, or six
single-ended channels, as programmed. The conversion
result of both channels is simultaneously available on
separate data lines, or in succession on one data line if only
one serial port is available.
2.
High Throughput with Low Power Consumption.
The AD7266 offers a 1.5 MSPS throughput rate with 11.4 mW
maximum power dissipation when operating at 3 V.
3.
The AD7266 offers both a standard 0 V to VREF input range
and a 2 × VREF input range.
4.
No Pipeline Delay.
The part features two standard successive approximation
ADCs with accurate control of the sampling instant via a
CS input and once off conversion control.
