Overview
Ordering number: EN683D 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.
) .
Reference voltage Constant voltage output is available with external transistor owing to pin Vref 2 = 5 V.
