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. The RS1461 uses the supply voltage as a reference, enabling the device to operate with a full-scale input range of 0 to VDD. 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 by a chip select ( CS̅̅̅ ) pin, reduces the power consumption 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.
