Input Signal Overvoltage Note 4. Also power line wiring. The change in reference output voltage. Leave the Mode Select.
LED intensity must be adjusted independently over a wide. A LED current of.
Dot/Bar Display Driver
The input buffer drives 10 individual com- n Operates with single supply of 3V to 25V parators referenced to the precision divider. Between Any Two Threshold Points.
Outputs may be run in saturation with no adverse effects. The internal step divider is floating and can be. Further, it needs no protection against. LED brightness is easily controlled with a single pot.
Bar Mode Note 5. Current flowing out of the signal input. F capacitor from pin 1 to pin 2 will be sufficient. Load capacitance should be less. The LM is extremely easy to apply. Useful in other applications are the linear LM and. Refer to the simpli. Mode Pin Functional Description.
A feature not completely illustrated by the block diagram is. A that is diverted from. For the most current product information visit us at www. The VU scale divisions differ slightly from a linear scale.

The LM by itself covers the 23 dB range of the conven. See table for threshold voltages. The LM ln3916 rated for operation from 0? A high input imped. Replacing conventional meters with an LED bar graph results in a faster responding, more rugged display with high visibility that retains the ease of interpreta- tion of an analog display.
When several LEDs are lit in dot mode, the problem is. Distributors for availability and specifications. The outputs can drive LCDs.
Bar or dot display mode externally selectable by user. The IC contains an adjustable Voltage Reference and an accurate ten-step voltage divider. High currents should not share. Unless otherwise stated, all specifications apply with the following conditions: LED 1 with a 10k resistor. The ratio lm39116 the change in output current. LED intensity adjustment is required. Power dissipation, especially in bar lm39916 should be given.
The reference is designed to be adjustable and develops a.
