• Manufacturer Part Number: mlx90313
• Description: Programmable Ir Sensor Interface
• Manufacturer: ETC-unknow

Output drivers
The IROUT and TEMPOUT outputs can be connected to various signals available: The amplified analog
signals (IRINP-IRINN and TINP-TINN), the linearised object respectively ambient temperature signals, or
to the comparator circuitry. The IROUT and TEMPOUT pin drivers can source 1mA and sink 20 A and
are reverse voltage protected down to –5V relative to VSS. The available configurations are described in
table below.
