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 SPITM, QSPITM, MICROWIRETM, 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. These converters offer a shutdown mode, which can be used to trade throughput for power consumption. The ADC121S101/ 101S101/081S101 is 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. These products are designed for operation over the automotive/extended industrial temperature range of -40°C to +125°C.

Pin Descriptions
Pin No. ANALOG I/O 3 DIGITAL I/O 4 5 6 POWER SUPPLY Positive supply pin. These pins should be connected to a quiet +2.7V to +5.25V source and bypassed to GND with 0.1 µF and 1 µF monolithic capacitors located within 1 cm of the power pin. The ADC121S101/101S101/081S101 uses this power supply as a reference, so it should be thoroughly bypassed. The ground return for the supply. SCLK SDATA CS Digital clock input. The range of frequencies for this input is 10 kHz to 20 MHz, with guaranteed performance at 20 MHz. This clock directly controls the conversion and readout processes. Digital data output. The output words are clocked out of this pin by the SCLK pin. Chip select. A conversion process begins on the falling edge of CS. VIN Analog input. This signal can range from 0V to VDD.
