MAX1110, MAX1111 +2.7V, Low-Power, Multichannel, Serial, 8-Bit ADCs

Description

The MAX1110/MAX1111 are low-power, 8-bit, 8-channel analog-to-digital converters (ADCs) that 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 V_DD. 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 SHDN-bar input pin. Accessing the serial interface automatically powers up the device.

The MAX1110 is available in 20-pin SSOP and DIP packages. The MAX1111 is available in small 16-pin QSOP and DIP packages.
