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.
