Texas Instruments ADCS7477AIMFX/NOPB

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 VDD. 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.
