ADC121S101/ADC101S101/ADC081S101 1MSPS, 12-/10-/8-Bit A/D Converters in SOT-23 June 2004 ADC121S101/ADC101S101/ADC081S101 1MSPS, 12-/10-/8-Bit A/D Converters in SOT-23 General 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 VDD. The conversion rate is determined from the serial clock (SCLK) speed.
