Philips Semiconductors Product specification

Triple video driver hybrid amplifier CR5427

FEATURES

• Transition times (10 to 90%)
with 45 V (p-p) swing
and CL= 10 pF:
rise time (typ.) 3 ns
fall time (typ.) 3 ns

• Very low power consumption:
7 Watt with 25 MHz square wave

• Minimum small signal bandwidth:
100 MHz

• Very fast slew rate 12000 V/µs

• Excellent grey-scale linearity

• Internal supply decoupling per

channel for optimum EMI
performance and minimal crosstalk

• Gold metallization ensures
excellent reliability

• No negative supply required in the
final stage.

APPLICATIONS

• Cathode-ray tube (CRT) drivers in
high-resolution colour monitors

• For 1280 x 1024 pixels (good
picture quality) with single PNP
buffer

• For 1024 x 768 pixels (acceptable
picture quality) when directly driven
from the video pre-amp IC.

DESCRIPTION
