CLC114
Quad, Low Power Video Buffer
General Description
The CLC114 is a high performance, close loop quad buffer
intended for power sensitive applications. Requiring only
30mW of quiescent power dissipation per channel (
supplies), the CLC114 offers a small signal bandwidth of
200MHz (0.5Vpp) and a slew rate of 450V/µs.
Designed specifically for high density crosspoint switch and
analog multiplexer applications, the CLC114 offers excellent
linearity and wide channel isolation (62dB
a typical crosspoint switch load, the CLC114 offers differen-
tial gain and phase performance of 0.08% and 0.1% gain
flatness through 30MHz is typically 0.1dB.
With its patented closed loop topology , the CLC114 has
significant performance advantages over conventional open
loop designs. Applications requiring low output impedance
and true unity gain stability through very high frequencies
(active filters, dynamic load buffering, etc.) Will benefit from
the CLC114’s superior performance.
Constructed using an advanced, complementary bipolar pro-
cess and National’s proven high speed architectures, the
CLC114 is available in several versions to meet a variety of
requirements.
