Philips Semiconductors Product specification
Triple video driver hybrid amplifier CR6929A
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
• Small 11-pin package
• Optimized for low supply voltages up to 90 V
• Design optimized for excellent smearing performance
• Low power consumption: 12 W with 25 MHz square
wave
• Gold metallization ensures excellent reliability.
DESCRIPTION
The CR6929A is a 3-channel hybrid RGB-amplifier module
in an 11-pin SOT451A package. Being an Active Load
amplifier, the CR6929A combines a high bandwidth with a
relatively low and constant dissipation. It is the
pin-compatible 11-pin successor to the 12-pin CR6928A
and CR6727A modules.
An optimized design, together with innovative application
recommendations, ensure excellent smearing
performance.
APPLICATIONS
• High-end CRT monitors with pixel frequencies up to
250 MHz.
