MECHANICAL DATA
Pinning:
1, 4, 5= N.C., 2 = VS, 3 = OUT, 6, 8 = GND, 7 = IN
FEATURES
• Carrier-out-function: carrier frequency and
burst length accurately correspond to the input
signal
• AC coupled response from 20 kHz to 60 kHz;
all data formats
• Small QFN package with 2 mm width
• Can be used with either a photodiode or an IR emitter in
forward or reverse polarity
• AC coupled input is insensitive to DC photocurrents
• Material categorization: for definitions of compliance
please see www.vishay.com/doc?99912
ESD
• To maximize the sensitivity, the TIA input pin has minimal
ESD protection. Care should be taken never to touch or
otherwise expose this pin to an adverse ESD source. The
ESD protection conforms to Class 1B
DESCRIPTION
The VSOP98260 is designed for use in an IR learning
application together with a photo PIN diode or IR LED as
optical detector. It is compatible with all data formats for IR
remote control. On the other hand it is immune to current
caused by light sources such as tungsten bulbs or
fluorescent lamps.
