The ADC128S102 is a low-power, eight-channel CMOS 12-bit analog-to-digital converter specified for conversion throughput rates of 500 ksps to 1 MSPS. 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 compatible with several standards, such as SPI, QSPI, MICROWIRE, and many common DSP serial interfaces.
●The ADC128S102 may be operated with independent analog and digital supplies. The analog supply (VA) can range from +2.7 V to +5.25 V, and the digital supply (VD) can range from +2.7 V to VA. Normal power consumption using a +3-V or +5-V supply is 2.3 mW and 10.7 mW, respectively. The power-down feature reduces the power consumption to 0.06 µW using a +3-V supply and 0.25 µW using a +5-V supply.
●The ADC128S102 is packaged in a 16-lead TSSOP package. Operation over the extended industrial temperature range of 40°C to +105°C is ensured.
