Philips Semiconductors Product specification

Triple video driver hybrid amplifier CR6929

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: 11 W with 25 MHz square

wave

• Gold metallization ensures excellent reliability.

DESCRIPTION

The CR6929 is a 3-channel hybrid RGB-amplifier module
in an 11-pin SOT451A package. Being an Active Load
amplifier, the CR6929 combines a high bandwidth with a
relatively low and constant dissipation. It is the
pin-compatible 11-pin successor to the 12-pin CR6928
and CR6727 modules.

An optimized design, together with innovative application
recommendations, ensure excellent smearing
performance.

APPLICATIONS

• High-end CRT monitors with low static dissipation and
pixel frequencies up to 250 MHz.

A member of the ‘29-family’ of active loads, the CR6929 is
optimized for low static dissipation. Other ‘29-family’
members are designed for higher bias currents, this being
