ADCS7478AIMF

Product Summary

The ADCS7478AIMF is a low power, monolithic CMOS 12-, 10- and 8-bit analog-to-digital converter that operates at 1 MSPS. The ADCS7478AIMF is a dropin replacement for the ADCS7478AIMF. The ADCS7478AIMF 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 ADCS7478AIMF 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. The ADCS7478AIMF offers a shutdown mode, which can be used to trade throughput for power consumption. The ADCS7478AIMF 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. The ADCS7478AIMF is available in a 6-lead, SOT-23 package and in a 6-lead LLP, both of which provide an extremely small footprint for applications where space is a critical consideration. The ADCS7478AIMF is designed for operation over the automotive/extended industrial temperature range of -40℃ to +125℃.
