ADC081S051 Single Channel, 500 kSPS, 8-Bit A/D Converter
General Description
The ADC081S051 is a low-power, single 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 ADC081S051 is fully specified over a sample rate range of 200 kSPS to 500 kSPS.
The converter is based on a successiveapproximation register architecture with an internal trackand-hold circuit.
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 ADC081S051 operates with a single supply that can range from +2.
7V to +5.
25V.
Normal power consumption using a +3V or +5V supply is 2.
9 mW and 10.
5 mW, respectively.
The power-down feature reduces the power consumption to as low as 2.
6 µW using a +5V supply.
The ADC081S051 is packaged in an 6-lead LLP package.
Operation over the industrial temperature range of −40˚C to +85˚C is guaranteed.
