1FEATURES DESCRIPTIONThe ADC082S021 is a low-power, two-channel
Specified Overa Rangeof Sample Rates. CMOS 8-bit analog-to-digital converter witha high-
• Two Input Channels speed serial interface. Unlike the conventional
Variable Power Management practiceof specifying performanceata single sample
rate only, the ADC082S021is fully specified overa
• Single Power Supply with 2.7V- 5.25V Range sample rate rangeof 50 ksps to 200 ksps. The
converteris based upona successive-approximation
KEY SPECIFICATIONS register architecture with an internal track-and-hold
DNL: ±0.04 LSB (typ) circuit.It canbe configuredto accept oneor two input
signalsat inputs IN1 and IN2.
• INL: ±0.04 LSB (typ) SNR: 49.6 dB (typ) The output serial data is straight binary, andis
compatible with several standards, such as SPI™,
• Power Consumption: QSPI™, MICROWIRE, and many common DSP
– 3V Supply 1.6 mW (typ) serial interfaces.
5V Supply 5.8 mW (typ) The ADC082S021 operates witha single supply that
can range from +2.7V to +5.25V. Normal power
APPLICATIONS consumption usinga +3Vor +5V supplyis 1.6 mW
Portable Systems and 5.8 mW, respectively. The power-down feature
reduces the power consumptionto just 0.12µ W using
• Remote Data Acquisition a +3V supply,or 0.35µ W usinga +5V supply.
• Instrumentation and Control SystemsThe ADC082S021is packagedin an 8-lead VSSOP
package. Operation over the industrial temperature
rangeof −40°Cto +85°C.
