ADCS7476/ADCS7477/ADCS7478

1MSPS, 12-/10-/8-Bit A/D Converters in 6-Lead SOT-23

General Description

Features

n Variable power management

n Packaged in 6-lead, SOT-23

n Power supply used as reference

n Single +2.7V to +5.25V supply operation

The ADCS7476, ADCS7477, and ADCS7478 are low power,

monolithic CMOS 12-, 10- and 8-bit analog-to-digital con-

verters that operate at 1 MSPS. The ADCS7476/77/78 are

drop-in replacements for Analog Devices’ AD7476/77/78.

Each device is based on a successive approximation regis-

ter architecture with internal track-and-hold. The serial inter-

™

n SPI /QSPI /MICROWIRE /DSP compatible

™

face is compatible with several standards, such as SPI

The ADCS7476/77/78 uses the supply voltage as a refer-

ence. This enables the devices 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 ADCS7476/77/78 is operated with

a single supply that can range from +2.7V to +5.25V. Normal

power consumption during continuous conversion, using a

+3V or +5V 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

+5V supply. All three converters are packaged in a 6-lead,

SOT-23 package that provides an extremely small footprint

for applications where space is a critical consideration.

These products are designed for operation over the

automotive/extended industrial temperature range of −40˚C

to +125˚C.
