Variable gain amplifier for signal-chain conditioning
The Texas Instruments LMH6521SQE/NOPB is a Variable Gain Amplifier (VGA) designed for signal processing applications where gain needs to be adjusted dynamically or set to a precise level. It comes in a 32-WFQFN Exposed Pad package (supplier device package 32-WQFN, 5x5 mm), surface-mount for compact board layouts.
Active lifecycle and compliance — no near-term EOL risk
ROHS3 compliance is confirmed, which covers the current EU RoHS exemption list. For designs that need a VGA in a 5x5 QFN footprint with active manufacturer support, this part is a straightforward BOM line to qualify.
Package and mounting — 32-WFQFN with exposed pad
The 32-WFQFN Exposed Pad package (5x5 mm body) requires a thermal pad connection to the PCB ground plane for adequate heat dissipation.
