資料

The ADCS7476, ADCS7477, and ADCS7478 are low power, monolithic CMOS 12-, 10- and 8-bit analog-to-digital converters 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 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 ADCS7476/77/78 uses the supply voltage as a reference, enabling the devices 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 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 available in a 6-lead, SOT-23 package and in a 6-lead WSON, both of which provide 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.
