• 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.
A member of the ‘29-family’ of active loads, the CR6929A
is intended for the highest monitor performance. Other
‘29-family’ members are intended for lower static
dissipation (CR6929) or lower supply voltages (CR6729A).

Rlevel and Rbias are intended to achieve the required output level and to optimize the frequency smearing performance.
Rlevel has to be adjusted to the required output level (approximately 2 kΩ at VS = −12 V).
Rbias has to be tuned for the best high frequency smearing performance (200 MHz burst).
