3 Description
The ADCS7476, ADCS7477, and ADCS7478 devices
are low power, monolithic CMOS 12-, 10-, and 8-bit
analog-to-digital converters that operate at 1 MSPS.
The ADCS747x devices are a drop-in replacement for
Analog Device's AD747x. Each device is based on a
successive approximation register architecture with
internal track-and-hold. The serial interface is
compatible with several standards, such as SPI,
QSPI, MICROWIRE, and many common DSP serial
interfaces.
The ADCS747x uses the supply voltage as a
reference, enabling the device to operate with a full-
scale input range of 0 to V
DD
. The conversion rate is
determined from the serial clock (SCLK) speed.
These converters offer a shutdown mode, which can
be used to trade throughput for power consumption.
The ADCS747x is operated with a single supply that
can range from 2.7 V to 5.25 V. Normal power
consumption during continuous conversion, using a
3-V or 5-V supply, is 2 mW or 10 mW respectively.
The power-down feature, which is enabled by a chip
select (CS) pin, reduces the power consumption to
under 5 µW using a 5-V supply. All three converters
are available in a 6-pin SOT-23 package, which
provides an extremely small footprint for applications
where space is a critical consideration. These
products are designed for operation over the
automotive and extended industrial temperature
range of −40°C to 125°C.
