HA1-5004-5 Datasheet 100MHz Current Feedback Amplifier

Manufacturer: Intersil (now Renesas)

Overview

The design is based on current-mode feedback which allows the amplifier to achieve higher closed loop bandwidth than voltage-mode feedback operational amplifiers.

Since feedback is employed, the HA-5004 can offer better gain accuracy and lower distortion than open loop buffers.

Key Features

  • have been designed in for added value. A thermal overload feature protects the part against excessive junction temperature by shutting down the output. If this feature is not needed, it can be inhibited via a TTL input (TOI). A TTL chip enable/disable (OE) is also provided; when the chip is disabled its output is high impedance. Finally, an open collector output flag (TOL) is provided to indicate the status of the chip. The status flag goes low to indicate when the chip is disabled due to either t.
