LB1409
Level Meter Driver for 9 LEDs
Applications
. AC level meters such as VU meters.
. DC level meters such as signal meters.
Functions
. Display
Nine red or green LEDs display the input level in the shape
of a bar.
. Input amplifier
Wide application is available owing to built-in DC amplifier
whose gain is variable with external resistors.
. Comparator level
Setting is made by steps of 3 dB as follows.
–18 dB, –15 dB, –12 dB, –9 dB, –6 dB, –3 dB, 0 dB,
+3 dB, +6 dB
. Supply voltage
The recommended supply voltage range is so wide as 5.5 V
to 16 V.
(If pin Vref 2 is used, 7 V to 16 V.)
. Reference voltage
Constant voltage output is available with external transistor
owing to pin Vref 2 = 5 V.
