EL5396C - Preliminary
Triple 400MHz Fixed Gain Amplifier
Features
* 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)
General Description
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. 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 150A 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 ---40C to +85C.
Applications
* * * * * * Video Amplifiers Cable Drivers RGB Amplifiers Test Equipment Instrumentation Current to Voltage Converters
