LMH6521SQE/NOPB TI Dual DVGA | 32-WQFN (5x5) | 1.2GHz BW, 25dB Gain

Product Overview

The LMH6521SQE/NOPB is a high-performance dual-channel digitally controlled variable gain amplifier (DVGA) from Texas Instruments. It is designed for applications requiring wide bandwidth, high linearity, and precise gain control. The device operates over a supply range of 4.75V to 5.25V and features a 3-wire serial interface for gain programming. With a bandwidth of 1.2GHz and a gain range of -5.5dB to 25dB in 0.5dB steps, it is ideal for high-speed communication systems.
