PRODUCT HIGHLIGHTS

GENERAL DESCRIPTION

1. Operation with 2.7 V to 5.25 V Power Supplies.

The AD7441/AD7451¹are, respectively, 10-/12-bit high speed,

low power, single-supply, successive approximation (SAR),

analog-to-digital converters (ADCs) that feature a pseudo

differential analog input. These parts operate from a single

2.7 V to 5.25 V power supply and achieve very low power

dissipation at high throughput rates of up to 1 MSPS.

2. High Throughput with Low Power Consumption.

With a 3 V supply, the AD7441/AD7451 offer 4 mW maxi-

mum power consumption for a 1 MSPS throughput rate.

3. Pseudo Differential Analog Input.

4. Flexible Power/Serial Clock Speed Management.

The conversion rate is determined by the serial clock,

allowing the power to be reduced as the conversion time

is reduced through the serial clock speed increase. These

parts also feature a shutdown mode to maximize power

efficiency at lower throughput rates.

The AD7441/AD7451 contain a low noise, wide bandwidth,

differential track-and-hold (T/H) amplifier that handles input

frequencies up to 3.5 MHz. The reference voltage for these

devices is applied externally to the V_REFpin and can range from

100 mV to V_DD, depending on the power supply and what suits

the application.

5. Variable Voltage Reference Input.

6. No Pipeline Delays.

The conversion process and data acquisition are controlled

using

with microprocessors or DSPs. The input signals are sampled

and the serial clock, allowing the device to interface

7. Accurate Control of Sampling Instant via

Once-Off Conversion Control.
