ADC081S101CISD Description

The ADC121S101, ADC101S101, and ADC081S101 are low power, monolithic CMOS 12-, 10- and 8-bit analog-to-digital converters that operate at 1 MSPS. Each device is based on a successive approximation register architecture with internal track-and-hold. The serial interface is compatible with several standards, such as SPI?, QSPI?, MICROWIRE?, and many common DSP serial interfaces.

The ADC121S101/101S101/081S101 uses the supply voltage as a reference. This enables the devices to operate with a full-scale input range of 0 to V_DD. The conversion rate is determined from the serial clock (SCLK) speed. These converters offer a shutdown mode, which can be used to trade throughput for power consumption. The ADC121S101/101S101/081S101 are operated with a single supply that can range from +2.7V to +5.25V. Normal power consumption during continuous conversion, using a +3V or +5V supply, is 2 mW or 10 mW, respectively. The power down feature, which is enabled by a chip select (CS#) pin, reduces the power consumption to under 5 µW using a +5V supply. All three converters are available in a 6-lead SOT-23 package, which provides an extremely small footprint for applications where space is a critical consideration. The ADC081S101 is also available in a 6-lead LLP package. These products are designed for operation over the industrial temperature range of -40°C to +85°C, with some parameters specified to +125°C for the ADC121S101.
