LB1416 36 five sections and Ten-segment level display a

A common single five lamp drive circuit is the LB1416/26/36, which is packaged in a double row of finned-line 14 pins. The circuit contains two input amplifiers and five voltage comparators, allowing it to drive both AC and DC meters, as well as light-emitting diodes (LEDs). With two inputs, it can display single-output levels and is suitable for dual-output power supply voltage level displays, accommodating a wide voltage range from 5.5V to 16V. The internal amplifier features two and a half crossing rectifiers that provide a constant excitation current for the LEDs, which can be adjusted for brightness using an external resistor. The LB1416/26/36 operates within a supply voltage range of 5.5V to 16V and has a supply current of 12mA. The circuit configuration, as illustrated in Figure 4-49, consists of five segments driven by the LB1416/26/36. It has two inputs but only one set of output terminals. When used as dual display drivers, it is essential to ensure the consistency of the two input signals being displayed. Each channel can be adjusted separately; for instance, when adjusting the right channel, a 0dB signal should be input at the right sound channel terminal, while the 51kΩ potentiometer should be used to make the LED (Lm) illuminate. Similarly, a 0dB signal can be input into the left channel, following the same adjustment procedure to light up LED (LD3). The LB1426 and LB1436 can be adjusted using the same method.

The LB1416/26/36 circuit is designed to provide a versatile solution for visual display applications, particularly in audio level monitoring and other electronic instrumentation. The dual input configuration allows for simultaneous monitoring of two different signals, making it highly effective in scenarios where comparative analysis is required. The use of voltage comparators enhances the circuit's ability to accurately reflect the voltage levels of the inputs, ensuring that the corresponding LEDs illuminate in response to the input signals.

The internal architecture of the LB1416/26/36 includes precision amplifiers that amplify the input signals before they are processed by the comparators. This amplification stage is critical for ensuring that even low-level signals can be effectively displayed. The incorporation of crossing rectifiers aids in converting AC signals to DC, making the circuit adaptable to various input types.

Adjustability is a key feature of this circuit, allowing users to fine-tune the brightness of the LEDs according to their specific requirements. The external resistor used for current control plays a vital role in defining the intensity of the LED output, which can be crucial in applications where visibility is important.

In summary, the LB1416/26/36 circuit represents a well-engineered solution for driving multiple LEDs in response to varying input signals, with features that support dual-channel operation and adjustable output levels. Its design principles ensure reliable performance across a broad range of applications, from audio systems to general-purpose voltage monitoring.Another common single five lamp drive circuit is: LB1416/26/36, the circuit is a double row of finned-line 14 pin package.
