Converter
1 Features
3 Description
The ADC128S102 device is a low-power, eight-
channel CMOS 12-bit analog-to-digital converter
specified for conversion throughput rates of 50 kSPS
to 1 MSPS. The converter is based on a successive-
approximation 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.

Key Specifications
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.
