GENERAL DESCRIPTION
The AD7476/AD7477/AD7478 are, respectively, 12-bit, 10-bit,
and 8-bit, high speed, low power, successive-approximation
ADCs. The parts operate from a single 2.35 V to 5.25 V power
supply and feature throughput rates up to 1 MSPS. The parts
contain a low noise, wide bandwidth track-and-hold amplifier
that can handle input frequencies in excess of 6 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 the conversion is also initiated at this
point. There are no pipeline delays associated with the part.
The AD7476/AD7477/AD7478 use advanced design techniques
to achieve very low power dissipation at high throughput rates.
The reference for the part is taken internally from V
DD
.
This
allows the widest dynamic input range to the ADC. Thus the
analog input range for the part is 0 V to V
DD
. The conversion
rate is determined by the SCLK.
PRODUCT HIGHLIGHTS
1. First 12-/10-/8-Bit ADCs in a SOT-23 Package.
2. High Throughput with Low Power Consumption.
3. 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. This allows the average power consumption
to be reduced while not converting. The part also features a
shutdown mode to maximize power efficiency at lower
throughput rates. Current consumption is 1
μ
A maximum
when in shutdown.
4. Reference Derived from the Power Supply.
5. 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.
