LM2904DR2G Dual Operational Amplifier for Whatsminer P21 Power Supply Repair

LM2904DR2G Dual Operational Amplifier for Whatsminer P21 PSU Repair

The LM2904DR2G is a low-power dual operational amplifier designed for single-supply operation, making it an ideal replacement component for Whatsminer P21 power supply units. It operates reliably over a wide supply voltage range and is commonly used in control, feedback, and signal conditioning circuits inside mining PSUs.

Thanks to its low quiescent current and common-mode input range that includes the negative supply, the LM2904DR2G eliminates the need for external biasing components in many power management designs, improving system stability and efficiency.

Reliable Low-Power Dual Op-Amp for Mining Power Supplies

The LM2904DR2G can operate from supply voltages as low as 3V and as high as 32V, providing excellent flexibility for PSU designs. It features continuous output short-circuit protection, low input bias current, and built-in ESD protection, ensuring long-term reliability in demanding mining environments.
