Monolithic Digital IC
LB1409 Level Meter Driver for 9 LEDs
Applications
Package Dimensions
unit : mm
. AC level meters such as VU meters. . DC level meters such as signal meters.
Functions
3064-DIP16
[LB1409]
. 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 SANYO : DIP16
. 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.)
