About the Product

SGM8304 Voltage Amplifier Module for Antminer S21, S19XP, S21XP & T21 Hash Board Repair

The SGM8304 Voltage Amplifier Conversion Module is a brand-new replacement module designed for Antminer S21, S19XP, S21XP and T21 hash boards. This module replaces the original SGM8304 operational amplifier circuit used for voltage signal amplification and regulation on the hash board.

Engineered for stable signal processing and precise voltage amplification, this module restores normal hash board operation when the original amplifier IC becomes faulty or unstable. It ensures accurate signal conversion within the power regulation feedback circuit, helping maintain optimal mining performance.

Reliable Voltage Signal Amplification for Antminer Hash Boards

The SGM8304 operational amplifier features high gain, frequency compensation, and single-supply operation. By stabilizing voltage feedback signals, this module helps improve hash board efficiency and prevents abnormal voltage behavior that can reduce hashrate or cause board instability.

This ready-to-install module simplifies maintenance and reduces repair time compared to direct IC-level replacement.
