____________________________Fe a t u re s  
The MAX1110/MAX1111 are low-power, 8-bit, 8-chan-  
nel 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 MAX1110s 8 analog inputs and the  
MAX1111s 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-inter-  
face clock. The full-scale analog input range is deter-

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 ha ve a s oftwa re -p rog ra m-  
mable, 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 input pin. Accessing the serial interface automat-  
ically powers up the device.
