LA1407
LA1417
Overview
Functions
Monolithic Digital IC
AC/DC Voltage Level Meter
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
