Description
The MLX90601B is a versatile IR thermometer
module, which performs signal conditioning,
linearisation and ambient temperature
compensation. The module is built around the
MLX90313 IR sensor interface, which uses high
performance chopper stabilized amplifiers,
providing excellent noise performance. The
sensing element is the MLX90247 discrete IR
thermopile.
The module is delivered factory calibrated. The
output is an absolute analog voltage output for
both sensor ambient temperature and the object
temperature. The REL1 output is the open drain
relay driver output available in MLX90313.

at this pin is a linear representation of Tambient,
the temperature of the IR sensor, as measured
by the PTC inside MLX90247. The driver can
source at least 1mA and sink at least 20µA
to/from an external load.

REL1
Open drain relay driver output. The typical on-

The comparator is a digital comparator, with a
resolution of 12 bits. By default the input polarity
is inverting. Threshold and hyteresis values are
version dependent, as indicated below. These
settings can be changed by factory programming
on request.
