ADC088S052 Datasheet | National Semiconductor

Description The ADC088S052 is a low-power, eight-channel CMOS 8-bit analog-to-digital converter specified for conversion throughput rates of 200 k SPS to 500 k SPS. The converter is based on a successive-approximation register architecture with an internal track-and-hold circuit. It can be configured to accept up to eight input signals at inputs IN0 through IN7. The output serial data is straight binary and is patible .. with several standards, such as SPI™, QSPI™, MICROWIRE™, and many mon DSP serial interfaces. The ADC088S052 may be operated with independent analog and digital supplies. The analog supply (VA) can range from +2.7V to +5.25V, and the digital supply (VD) can range from +2.7V to VA. Normal power consumption using a +3V or +5V supply is 1.2 m W and 6.5 m W, respectively. The powerdown feature reduces the power consumption to 0.03 µW using a +3V supply and 0.15 µW using a +5V supply. The ADC088S052 is packaged in a 16-lead TSSOP package. Operation over the extended industrial temperature range of - 40˚C to +105˚C is guaranteed.
