Use
Indicates tuning condition of FM receiver by means of 5
mode – 3 LEDs.
Features
3 LEDs display 5 mode tuning condition.
Since the LEDs are driven under constant current supply,
the LED current varys as shown below when two LEDs
are lighted on simultaneously. This causes their bright-
ness to vary, and enables the dynamic indication.
Desired tuning width can be set as the threshold width of
window comparator is variable externally.
No switching radiation can be made as LED current
changes over linearly.
Blanking at station interval and AM reception is easy to
set by blanking pin.
Direct interface can be made to IF IC using quadrature
detector (ex. LA1231, LA1140, etc.)
Single-ended 9 pin package with small mounting area.
