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