Philips Semiconductors Product specification

Triple video driver hybrid amplifier CR6927

FEATURES

• Transition times (10 to 90%)
with 45 V (p-p) swing
and CL= 10 pF:
rise time (typ.) 2.5 ns
fall time (typ.) 2.1 ns

• Low power consumption:
11 W with 25 MHz square wave

• Minimum small signal bandwidth:
140 MHz at 1 V (p-p) or
120 MHz at 40 V (p-p)

• Very fast slew rate: 16000 V/µs

• Internal low frequency smearing

compensation

• Excellent grey-scale linearity

• Unconditional stability

• Gold metallization ensures

excellent reliability.

APPLICATIONS

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