ELANTEC EL5396C

Triple 400MHz Fixed Gain Amplifier
Features
General Description
• Gain selectable (+1, -1, +2)
• 400MHz -3dB Bandwidth (AV = 1,
2)
• 9mA supply current (per amplifier)
• Single and dual supply operation,
from 5V to 10V
• Power-down
• Available in 16-pin QSOP package
• Single (EL5196C) available
• 200MHz, 3mA product available
(EL5197C, EL5397C)
The EL5396C is a triple channel, fixed gain amplifier with a bandwidth of 400MHz, making these amplifiers ideal for today’s high
speed video and monitor applications. The EL5396C features internal
gain setting resistors and can be configured in a gain of +1, -1 or +2.
The same bandwidth is seen in both gain-of-1 and gain-of-2
applications.

EL5396C - Preliminary
The EL5396C can be run from a single or dual supply voltage of 5V to
10V and consumes just 9mA of supply current per channel. Each
channel of the EL5396C has a disable. Upon being disabled, the outputs are tri-stated and the power supply current reduces to less than
150µA per amplifier. Allowing the CE pin to float, or applying a low
logic level will enable the amplifier.
For applications where board space is critical, the EL5396C is offered
in the 16-pin QSOP package, as well as a 16-pin SO. The EL5396C is
specified for operation over the full industrial temperature range of ---40°C to +85°C.
