GENERAL DESCRIPTION

DRIVE

The AD7923 is a 12-bit, high speed, low power, 4-channel, suc-

cessive approximation (SAR) ADC. It operates from a single

2.7 V to 5.25 V power supply and features throughput rates up to

200 kSPS. It contains a low noise, wide bandwidth track-and-hold

amplifier that can handle input frequencies in excess of 8 MHz.

PRODUCT HIGHLIGHTS

1. High Throughput with Low Power Consumption.

The AD7923 offers up to 200 kSPS throughput rates. At the

maximum throughput rate with 3 V supplies, the AD7923

dissipates just 3.6 mW of power.

The conversion process and data acquisition are controlled by

and the serial clock, allowing the device to easily interface

with microprocessors or DSPs. The input signal is sampled on

2. Four Single-Ended Inputs with a Channel Sequencer.

the falling edge of ; the conversion is also initiated at this

3. Single-Supply Operation with V_DRIVEFunction.

The V_DRIVEfunction allows the serial interface to connect

directly to either 3 V or 5 V processor systems independent

point.

The AD7923 uses advanced design techniques to achieve very

low power dissipation at maximum throughput rates. At

maximum throughput rates, it consumes 1.2 mA maximum

with 3 V supplies and 1.5 mA maximum with 5 V supplies.

of AV_DD

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. The part also features various

shutdown modes to maximize power efficiency at lower

throughput rates. Current consumption is 0.5 μA

maximum when in full shutdown.

Through the configuration of the control register, the analog

input range can be selected as 0 V to REF_INor 0 V to 2 × REF_IN,

with either straight binary or twos complement output coding.

The AD7923 features four single-ended analog inputs with a

channel sequencer to allow a preprogrammed selection of

channels to be converted sequentially.

5. No Pipeline Delay.

The part features a SAR ADC with accurate control of the

The conversion time for the AD7923 is determined by the serial

clock, SCLK, frequency, since this is used as the master clock to

control the conversion. The conversion time can be as short as

800 ns with a 20 MHz SCLK.
