描述 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.特性 Variable Power Management Packaged in 6-Pin SOT-23 Power Supply Used as Reference Single 2.7-V to 5.25-V Supply Operation Compatible With SPI?, QSPI?, MICROWIRE?, and DSP Key Specifications Resolution With No Missing Codes (12-Bit, 10- Bit, and 8-Bit) Conversion Rate: 1 MSPS DNL: 0.5, ?0.3 LSB (Typical) INL: ±0.4 LSB (Typical) Power Consumption: 3-V Supply: 2 mW (Typical) 5-V Supply: 10 mW (Typical)
