The LMH6504 is a wideband, low power, variable gain amplifier from Texas Instruments. Its maximum gain is 80 dB, bandwidth is 10 MHz, and it can directly drive low impedance loads.
The LMH6504 is a DC‑coupled voltage‑controlled gain stage followed by a high‑speed current‑feedback op‑amp that can directly drive low‑impedance loads. It offers a gain adjustment range of up to 80 dB for frequencies below 10 MHz and maintains a flat gain response up to 150 MHz.
Designed for single‑supply operation, the device operates from 7 V to 12 V, consumes about 110 mW, and provides a high slew rate (>1500 V/µs) with a linear output current capability of 60 mA. Its small SO8 and MSOP8 packages make it suitable for space‑constrained applications.
