MAX1111:+2.7V、低功耗、多通道、串行8位ADC

功耗最低的8位、4/8通道ADC,内置基准

The MAX1110/MAX1111 low-power, 8-bit, 8-channel analog-to-digital converters (ADCs) feature an internal track/hold, voltage reference, clock, and serial interface. They operate from a single 2.7V to 5.5V supply and consume only 85µA while sampling at rates up to 50ksps. The MAX1110's 8 analog inputs and the MAX1111's 4 analog inputs are software-configurable, allowing unipolar/bipolar and single-ended/differential operation. Successive-approximation conversions are performed using either the internal clock or an external serial-interface clock. The full-scale analog input range is determined by the 2.048V internal reference, or by an externally applied reference ranging from 1V to VDD. The 4-wire serial interface is compatible with the SPI™, QSPI™, and MICROWIRE™ serial-interface standards. A serial-strobe output provides the end-of-conversion signal for interrupt-driven processors. The MAX1110/MAX1111 have a software-programmable, 2µA automatic power-down mode to minimize power consumption. Using power-down, the supply current is reduced to 6µA at 1ksps, and only 52µA at 10ksps. Power-down can also be controlled using the active-low SHDN input pin. Accessing the serial interface automatically powers up the device. The MAX1110 is available in a 20-pin SSOP package. The MAX1111 is available in a small 16-pin QSOP package.
