TDA4680 Overview
Key Specifications
Package: DIP
Max Voltage (typical range): 8.8 V
Min Voltage (typical range): 7.2 V
Length: 35.5 mm
Key Features
- Operates from an 8 V DC supply
- Black level clamping of the colour difference, luminance and RGB input signals with coupling-capacitor DC level storage
- Two fully-controlled, analog RGB inputs, selected either by fast switch signals or via I2C-bus
- Saturation, contrast and brightness adjustment via I2C-bus
- Same RGB output black levels for Y/CD and RGB input signals
- Automatic cut-off control with picture tube leakage current compensation
- Software-based automatic white level control or fixed white levels via I2C-bus
- Increased RGB signal bandwidths for progressive scan and 100 Hz operation (selected via I2C-bus)
- Two switch-on delays to prevent discolouration before steady-state operation
- Average beam current and peak drive limiting
