The ADCS7476/77/78 are drop-in replacements for • Single +2.7V to +5.25V Supply Operation Analog Devices' AD7476/77/78. Each device is based • SPI™/QSPI™/MICROWIRE™/DSP Compatible on a successive approximation register architecture with internal track-and-hold. The serial interface is APPLICATIONS compatible with several standards, such as SPI™, QSPI™, MICROWIRE™, and many common DSP • Automotive Navigation serial interfaces. • FA/ATM Equipment The ADCS7476/77/78 uses the supply voltage as a • Portable Systems reference, enabling the devices to operate with a full- • Medical Instruments scale input range of 0 to VDD. The conversion rate is • Mobile Communications determined from the serial clock (SCLK) speed. These converters offer a shutdown mode, which can • Instrumentation and Control Systems be used to trade throughput for power consumption. The ADCS7476/77/78 is operated with a single KEY SPECIFICATIONS supply that can range from +2.7V to +5.25V. Normal • Resolution with no Missing Codes 12/10/8 bits power consumption during continuous conversion, using a +3V or +5V supply, is 2 mW or 10 mW • Conversion Rate 1 MSPS respectively. The power down feature, which is • DNL +0.5, -0.3 LSB (typ) enabled by a chip select (CS) pin, reduces the power • INL ± 0.4 LSB (typ) consumption to under 5 µW using a +5V supply. All • Power Consumption three converters are available in a 6-lead, SOT-23 package and in a 6-lead WSON, both of which – 3V Supply 2 mW (typ) provide an extremely small footprint for applications – 5V Supply 10 mW (typ) 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.
