FAQs

What is TDA3845?

The TDA3845 is a vertical deflection output circuit for high-definition color television applications. It is designed to drive the deflection yoke of CRT (Cathode Ray Tube) monitors and TVs, providing vertical scanning functionality for the display.

How Does TDA3845 Work?

The TDA3845 operates by receiving vertical deflection signals from the TV system and amplifying them to drive the deflection yoke of the CRT monitor or TV. This vertical scanning function ensures the proper display of images on the screen by deflecting the electron beam accurately at a high frequency.

How Many Pins does TDA3845 have and What are the Functions of the Pinout Configuration?

The TDA3845 is housed in a 9-lead SIL (Single In-Line) package. The pinout configuration includes:

1. VCC: Power supply pin.
2. GND: Ground pin.
3. V3: Output stage power supply pin.
4. CFI: Flyback capacitor pin.
5. GCI: Flyback generator input pin.
6. OUT: Vertical output pin.
7. GND: Ground pin (connected to pin 2).
8. SAW: Sawtooth wave generator input pin.
9. V1: Output stage power supply pin.

What are the Pros and Cons of TDA3845?

Pros:

Designed for High-Definition: Specifically tailored for high-definition color television applications.
Vertical Deflection Functionality: Enables precise vertical scanning of the CRT display.
Compact Package: Housed in a 9-lead SIL package for space-efficient designs.
Integrated Functions: Combines multiple functions for vertical deflection in a single IC.

Cons:

Application Specific: Limited to vertical deflection applications in CRT monitors and TVs.
Obsolete Technology: May not be suitable for modern display technologies such as LCD or OLED.
External Components: Requires external components for complete CRT monitor design.

Are There Any Equivalents/Alternatives to TDA3845 for Recommendation?

The TDA8359J from STMicroelectronics is a similar vertical deflection output circuit for CRT applications.
Alternatives to the TDA3845 include the LA7845 from Sanyo and the STV9306 from STMicroelectronics.
