RS1461

1 MSPS, 12 Bit Single-Ended Analog-to-Digital Converter

1 FEATURES

3 DESCRIPTIONS

The RS1461 is a low power, monolithic CMOS 12-bit

analog-to-digital converter that operates at 1 MSPS. The

RS1461 is a drop-in replacement for Texas Instruments'

ADCS7476. This 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.

Key Specifications

The RS1461 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. This converter offers

a shutdown mode, which can be used to trade

throughput for power consumption. The RS1461 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 4.5mW or 11mW

respectively. The power-down feature, which is enabled

to under 5µW using a 5V supply. This converter is

available in a 6-pin SOT-23 package, which provides an

extremely small footprint for applications where space is

a critical consideration. This product is designed for

operation over the automotive and extended industrial

temperature range of -40°C to 125°C.
