LB1409M
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.
-18dB, -15dB, -12dB, -9dB, -6dB, -3dB, 0dB,+3dB, +6dB
Supply voltage
The recommended supply voltage range is so wide as 5.5V to 16V.
(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 = 5V
