6 provides a selectable current of -60mA or +300mA.
Channel 7 provides 90mA. Channels 8 and 9 provide a
selectable current of 15mA or 35mA. Connect DAC out-
puts in parallel to obtain additional current or to achieve
higher resolution. The device contains an internal refer-
ence.
An I
2
C-compatible interface drives the device with clock
rates of up to 400kHz. An active-high asynchronous CLR
input resets DAC codes to zero independent of the serial
interface. The device provides a separate power-supply
input for driving the interface logic.
The MAX5112 is specified over the -40NC to +105NC
temperature range, and is available in 3mm x 3mm,
36-bump WLP and 5mm x 5mm, 32-pin TQFN packages.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect device reliability.
