The MAX1112/MAX1113 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 4.5V to 5.5V supply and consume only 135μA while sampling at rates up to 50ksps. The MAX1112's 8 analog inputs and the MAX1113'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 4.096V 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 MAX1112/MAX1113 have a software-programmable, 2µA automatic power-down mode to minimize power consumption. Using power-down, the supply current is reduced to 13µA at 1ksps, and only 82µA 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 MAX1112 is available in a 20-pin SSOP package. The MAX1113 is available in a small 16-pin QSOP package.
