Description



Features:

. 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.


Application

. AC level meters such as VU meters
. DC level meters such as signal meters.
