General Description
The MAX1112/MAX1113 low-power, 8-bit, 8-channel
analog-to-digital converters (ADCs) feature an internal
track/hold, voltage reference, clock, and serial inter-
face. They operate from a single 4.5V to 5.5V supply
and consume only 135A 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-inter-
face clock. The full-scale analog input range is deter-
mined 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-program-
mable, 2A automatic power-down mode to minimize
power consumption. Using power-down, the supply
current is reduced to 13A at 1ksps, and only 82A at
10ksps. Power-down can also be controlled using the
SHDN input pin. Accessing the serial interface automat-
ically 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.
