GENERAL DESCRIPTION
The AD7475/AD74951 are 12-bit, high speed, low power,
successive-approximation ADCs that operate from a single
2.7 V to 5.25 V power supply with throughput rates up to
1 MSPS. They contain a low noise, wide bandwidth track-and-
hold amplifier that can handle input frequencies above 1 MHz.
The conversion process and data acquisition are controlled
using CS and the serial clock, allowing the devices to interface
with microprocessors or DSPs. The input signal is sampled on
the falling edge of CS and conversion is initiated at this point.
The conversion time is determined by the SCLK frequency.
There are no pipeline delays associated with the part.
The AD7475/AD7495 use advanced design techniques to
achieve very low power dissipation at high throughput rates.
With 3 V supplies and a 1 MSPS throughput rate, the AD7475
consumes just 1.5 mA, while the AD7495 consumes 2 mA.
With 5 V supplies and 1 MSPS, the current consumption is
2.1 mA for the AD7475 and 2.6 mA for the AD7495.
The analog input range for the parts is 0 V to REF IN. The 2.5 V
reference for the AD7475 is applied externally to the REF IN
pin, while the AD7495 has an on-board 2.5 V reference.

PRODUCT HIGHLIGHTS
1.
The AD7475 offers 1 MSPS throughput rates with 4.5 mW
power consumption.
2.
Single-supply operation with VDRIVE function. The
AD7475/AD7495 operate from a single 2.7 V to 5.25 V
supply. The VDRIVE function allows the serial interface
to connect directly to either 3 V or 5 V processor systems
independent of VDD.
3.
Flexible power/serial clock speed management. The con-
version rate is determined by the serial clock, allowing the
conversion time to be reduced through the serial clock
speed increase. The parts also feature shutdown modes to
maximize power efficiency at lower throughput rates. This
allows the average power consumption to be reduced while
not converting. Power consumption is 1 μA when in full
shutdown.
4.
No pipeline delay. The parts feature a standard successive
approximation ADC with accurate control of the sampling
instant via a CS input and once-off conversion control.
