Note 1: Measurements for the TPS830(F) are based on a standard circuit which includes a 1000

−pF capacitor

between VO and GND to prevent oscillation.

Note 2: Standard transmitter

The TPS703(F) in this application has a short

Note 3: Transmission range L

Standard transmitter (TLN105B(F))

L is the maximum distance at which burst waves can be received from the transmitter unit, and at which

data can be processed by the receiver unit.

Note that when signals other than the recommended burst wave are transmitted, the transmission range

may be reduced or a malfunction may occur.

(*) The TLN105B(F) is used as the standard LED transmitter.

If the TLN231(F) is used instead, the transmission range is 1.2 times that of the TLN105B(F).

Example: 6m (with TLN105B(F)) ⇒ 10.1m (with TLN231(F))
