General Desc ription
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 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-inter-
face clock. The full-scale analog input range is deter-
mined 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-program-
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.
The MAX1110 is available in 20-pin SSOP and DIP
packages. The MAX1111 is available in small 16-pin
QSOP and DIP packages.
