3 Description
The ADC128S102 device is a low-power, eightchannel
CMOS 12-bit analog-to-digital converter
specified for conversion throughput rates of 50 kSPS
to 1 MSPS. The converter is based on a successiveapproximation
register architecture with an internal
track-and-hold circuit. The device 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.
