8-Channel, 50 kSPS to 1 MSPS, 12-Bit A/D Converter
General Description
The ADC128S102 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. 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 (V_A) can range from
+2.7V to +5.25V, and the digital supply (V_D) can range from
+2.7V to V_A. Normal power consumption using a +3V or +5V
supply is 2.3 mW and 10.7 mW, respectively. The power-
down feature reduces the power consumption to 0.06 µW
using a +3V supply and 0.25 µW using a +5V supply.
