14.1.TDA6109

14.1.1.General Description

The TDA6109JF includes three video output amplifiers in one plastic DIL-bent-SIL 9-pin medium power
(DBS9MPF) package (SOT111-1), using high-voltage DMOS technology, and is intended to drive the three
cathodes of a colour CRT directly. To obtain maximum performance, the amplifier should be used with black-
current control.

14.1.2.Features

· Typical bandwidth of 9.0 MHz for an output signal of 60 V (p-p)
· High slew rate of 1850 V/ms
· No external components required
· Very simple application
· Single supply voltage of 200 V
· Internal reference voltage of 2.5 V
· Fixed gain of 51
· Black-Current Stabilization (BCS) circuit
· Thermal protection.

14.2.27W401

14.2.1.Description
The M27W401 is a low voltage 4 Mbit EPROM offered in the two ranges UV (ultra violet erase) and
OTP (one time programmable). It is ideally suited for microprocessor systems requiring large data or
program storage and is organized as 524,288 by 8 bits. The M27W401 operates in the read mode with
a supply voltage as low as 2.7V at –40 to 8??C temperature range. The decrease in operating power
allows either a reduction of the size of the battery or an increase in the time between battery re-
charges.
The FDIP32W (window ceramic frit-seal package) has a transparent lid, which allows the user to ex-
pose the chip to ultraviolet light to erase the bit pat-tern. A new pattern can then be written to the
device by following the programming procedure. For application where the content is programmed only
one time and erasure is not required, the M27W401 is offered in PDIP32, PLCC32 and TSOP32 (8 x 20
mm) packages.
