Philips Semiconductors Product specification

Triple video driver hybrid amplifier CR6928

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 smearing compensation

• Excellent grey-scale linearity

• Unconditional stability

• Gold metallization ensures excellent reliability.

APPLICATIONS

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