Features Eight input channels Variable power management Independent analog and digital supplies SPI/QSPI ™/MICROWIRE ™/DSP compatible Packaged in 16-lead TSSOP Description The ADC108S052 is a low-power, eight-channel CMOS 10-bit analog-to-digital converter specified for conversion throughput rates of 200 ksps to 500 ksps. 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 ADC108S052 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 1.5 mW and 7.5 mW, respectively. The power-down feature reduces the power consumption to 0.09 µW using a +3V supply and 0.30 µW using a +5V supply. The ADC108S052 is packaged in a 16-lead TSSOP package. Operation over the extended industrial temperature range of −40°C to +105°C is guaranteed.

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
