ABSOLUTE MAXIMUM RATINGS PIN CONFIGURATION (Note 1)
Supply Voltage ...5.5V TOP VIEW Enable Voltage ...–0.3V to VCC + 0.3V V 1 10 FLTR CC Input Signal Power (Differential) ..15dBm IN+ 2 9 EN T DEC 3 8 DNC JMAX .. 125°C IN– 4 7 DNC Operating Temperature Range.. –40°C to 85°C GND 5 6 OUT Storage Temperature Range ... –65°C to 125°C DD PACKAGE 10-LEAD (3mm s 3mm) PLASTIC DFN CAUTION: This part is sensitive to electrostatic discharge. It TJMAX = 125°C, θJA = 43°C/W is very important that proper ESD precautions be observed EXPOSED PAD (PIN 11) IS GND, MUST BE SOLDERED TO PCB when handling the LT5570.
