MLX90615
Infra Red Thermometer
9 Unique Features
The MLX90615 is a ready-to use low-cost non contact thermometer provided by Melexis with output data
linearly dependent on the object temperature with high accuracy and extended resolution.
The user can program the internal object emissivity correction for objects with a low emissivity.
The MLX90615 is housed in standard TO46 package.
The low power consumption and sleep mode make the thermometer ideally suited for handheld mobile
applications.
The digital sensor interface can be either a PWM or an enhanced access SMBus compatible protocol.
Systems with more than 100 devices can be built with only two signal lines.

Figure 15: Preliminary accuracy of MLX90615 (Ta,To)
All accuracy specifications apply under settled isothermal conditions only and nominal supply voltage.
The accuracy in the range Ta 10ºC - 40ºC and To 32ºC - 42ºC is shown in diagram below. The accuracy
for the rest ranges is same as in previous diagram.
