The Analog Devices MAX6656MEE+ is a digital temperature sensor that measures both its own local die temperature and a remote diode-connected transistor. It reports readings over an I²C/SMBus interface with 7-bit resolution, making it a straightforward drop-in for thermal monitoring in systems that already have a two-wire bus.
Accuracy — what the ±1.5°C spec means for your measurement
The MAX6656MEE+ is rated at ±1.5°C accuracy in its best case, with a worst-case ±3°C over the full temperature and supply range.
Built-in control features reduce external components
This sensor integrates an output switch, a programmable temperature limit, shutdown mode, and standby mode. The output switch can directly drive a warning LED or a logic-level MOSFET for a fan without needing a separate comparator. The programmable limit lets you set an overtemperature threshold via the I²C bus, and the shutdown/standby modes drop power consumption when the system is idle. For a panel-builder or OEM integrator, these features mean fewer passives and less board area for the thermal management loop.
Package and mounting — 16-QSOP surface-mount footprint
The MAX6656MEE+ comes in a 16-pin QSOP package (3.90 mm body width, 0.154" pitch), surface-mount only.
