GENERAL DESCRIPTION
The AD7441/AD74511 are, 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.
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 VREF pin and can range from
100 mV to VDD, depending on the power supply and what suits
the application.
The conversion process and data acquisition are controlled
using CS and the serial clock, allowing the device to interface
with microprocessors or DSPs. The input signals are sampled
on the falling edge of CS when the conversion is initiated.
The SAR architecture of these parts ensures that there are no
pipeline delays.
1 Protected by U.S. Patent Number 6,681,332.
PRODUCT HIGHLIGHTS
1.
Operation with 2.7 V to 5.25 V Power Supplies.
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.
5.
Variable Voltage Reference Input.
6.
No Pipeline Delays.
7.
Accurate Control of Sampling Instant via CS Input and
Once-Off Conversion Control.
8.
ENOB > 10 Bits Typically with 500 mV Reference.
