Philips (Now NXP) TDA6107AJF Schematic [ru]
TDA6107AJF
Triple video output amplifier
Rev. 02 — 28 April 2005 Product data sheet
1. General description
The TDA6107AJF contains three video output amplifiers which are intended to drive the
three cathodes of a color CRT. The device is contained in a plastic DIL-bent-SIL 9-pin
medium power (DBS9MPF) package, and uses high-voltage DMOS technology.
To obtain maximum performance, the amplifier should be used with black-current control.
2. Features
■ Typical bandwidth of 5.5 MHz for an output signal of 60 V (p-p)
■ High slew rate of 900 V/µs
■ No external components required
■ Very simple application
■ Single supply voltage of 200 V
■ Internal reference voltage of 2.5 V
■ Fixed gain of 81
■ Black-Current Stabilization (BCS) circuit with voltage window from 1.8 V to 6 V and
current window from +100 µA to −10 mA
■ Thermal protection
■ Internal protection against positive flashover discharges appearing on the CRT

8.1 Thermal protection
The internal thermal protection circuit gives a decrease of the slew rate at high
temperatures: 10 % decrease at 130 °C and 30 % decrease at 145 °C (typical values on
the spot of the thermal protection circuit).
