Comparator Level at Ta = 25°C, V CC =12V
LB1407
LB1417
The LA1407 and LA1417 are AC/DC voltage level meter. The LB1407 is based on dB scale and the LB1417 is based on
linear scale respectively. The input level is indicated in the form of a bar by means of 7 LED’s.
• The LED current is made variable with an external resistor.
• An input amplifier is built in.
• A wide range of supply voltages is available from 5.5V
