描述 The ADC081S051 is a low-power, single channel CMOS 8-bit analog-to-digital converter with a high-speed serial interface. Unlike the conventional practice of specifying performance at a single sample rate only, the ADC081S051 is fully specified over a sample rate range of 200 ksps to 500 ksps. The converter is based on a successive-approximation register architecture with an internal track-and-hold circuit.The output serial data is straight binary, and is compatible with several standards, such as SPI?, QSPI?, MICROWIRE, and many common DSP serial interfaces.The ADC081S051 operates with a single supply that can range from +2.7V to +5.25V. Normal power consumption using a +3.6V or +5.25V supply is 1.6 mW and 8.5 mW, respectively. The power-down feature reduces the power consumption to as low as 2.6 μW using a +5.25V supply.The ADC081S051 is packaged in 6-lead WSON and SOT-23 packages. Operation over the industrial temperature range of ?40°C to +85°C is ensured.特性Specified Over a Range of Sample Rates 6-lead WSON and SOT-23 Packages Variable Power Management Single Power Supply with 2.7V ? 5.25V Range SPI?/QSPI?/MICROWIRE/DSP CompatibleKey Specifications DNL: +0.06 / ?0.045 LSB (Typ) INL: +0.06 / ?0.05 LSB (Typ) SNR: 49.6 dB (Typ) Power Consumption: 3.6V Supply: 1.6 mW (Typ) 5.25V Supply: 8.5 mW (Typ)
