ADC082S101
2 Channel, 1 MSPS, 8-Bit A/D Converter
General Description
The ADC082S101 is a low-power, two-channel CMOS 8-bit
analog-to-digital converter with a high-speed serial interface.
Unlike the conventional practice of specifying performance
at a single sample rate only, the ADC082S101 is fully speci-
fied over a sample rate range of 500 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 one or two input signals at inputs IN1
and IN2.
The output serial data is straight binary, and is compatible
with several standards, such as SPI
, QSPI
, MICROW-
IRE, and many common DSP serial interfaces.
The ADC082S101 operates with a single supply that can
range from +2.7V to +5.25V. Normal power consumption
using a +3V or +5V supply is 3.2 mW and 9.6 mW, respec-
tively. The power-down feature reduces the power consump-
tion to just 0.12 μW using a +3V supply, or 0.35 μW using a
+5V supply.
The ADC082S101 is packaged in an 8-lead MSOP package.
Operation over the industrial temperature range of 40C to
+85C is guaranteed.
