DESCRIPTION
The ADC108S022 is a low-power, eight-channel
CMOS 10-bit analog-to-digital converter specified for
conversion throughput rates of 50 ksps to 200 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 ADC108S022 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 1.1 mW and 6.4 mW, respectively. The power-down
feature reduces the power consumption to 0.09 μW
using a +3V supply and 0.3 μW using a +5V supply.
The ADC108S022 is packaged in a 16-lead TSSOP
package. Operation over the extended industrial
temperature range of −40°C to +105°C is ensured.
