Key Features

  • 10-channel LED dot/bar display driver with selectable display mode via pin
  • Analog input with internal voltage divider — no external resistors required for LED current setting
  • Drives up to 10 LEDs directly with built-in current regulation per channel
  • Available in 20-pin PLCC package (S-PQCC-J20) for compact PCB integration
  • JEDEC e3 compliant, RoHS compatible Texas Instruments device

Applications

The LM3914VX/NOPB is widely used in battery level indicators, audio VU meters, and signal strength displays where a linear analog bargraph or moving-dot LED readout is required. Its analog input interface makes it ideal for directly interfacing with sensors, potentiometers, or DAC outputs in industrial and consumer electronics. The selectable dot/bar mode and integrated LED current control simplify design in panel meters, test equipment, and power monitoring systems.

Frequently Asked Questions

What is the LM3914VX/NOPB and what does it do?

The LM3914VX/NOPB is a 10-channel analog dot/bar LED display driver IC from Texas Instruments. It accepts an analog input voltage and drives up to 10 LEDs in either dot mode (single LED lit) or bar graph mode (all LEDs up to the input level lit), making it ideal for level meters, battery indicators, and signal displays.

What is the package type and pin count of the LM3914VX/NOPB?

The LM3914VX/NOPB comes in a 20-pin Plastic Leaded Chip Carrier (PLCC) package, identified by the JESD-30 code S-PQCC-J20. This surface-mount package is suitable for compact PCB designs requiring robust LED driver functionality.

What are typical applications for the LM3914VX/NOPB?

Typical applications include audio VU meters, battery charge level indicators, signal strength displays, panel meters in test and measurement equipment, and industrial power monitors. Its analog input and integrated LED current regulation simplify design in any application requiring a visual bar or dot-level display.

How do you select between dot mode and bar mode on the LM3914VX/NOPB?

The LM3914VX/NOPB supports selectable dot mode or bar graph mode via a dedicated mode pin. Connecting the mode pin to the high supply enables bar mode where all LEDs up to the input level illuminate, while leaving it floating or connecting to ground enables dot mode where only a single LED lights at the measured level.
