Specifications of E981.03A38HB

• Rohs: yes
• Product Type: KNX/EIB Transceiver
• Operating Supply Voltage: 3.3 V
• Supply Current: 10 mA
• Maximum Power Dissipation: 1 W
• Maximum Operating Temperature: + 85 C
• Mounting Style: SMD/SMT
• Package / Case: QFN-32
• Minimum Operating Temperature: - 25 C

2 Recommended Operation Conditions
1) For telegram rates > 50% P
2) The lower limit is necessary for DC/ DC control.
The upper limit is a result of ripple considerations: voltage ripple is ESR * current ripple of LSPS.
3) I
4) Smaller C
5) Only necessary in case of the E981.03 being connected to a separate application module.
These components only ensuring to meet the absolute maximum rating in case of connecting and disconnecting the applica-
tion module. If the connector guarantees to connect GND potential first, the ESD protection is not needed.
6) For better elaboration of the ADC results a stable VIO is highly recommended.
7) High capacitance may affect the Reset / Power up Sequence time, as it is loaded with current limitation I
ELMOS Semiconductor AG reserves the right to change the detail specifications as may be required to permit improvements in the design of its products.
