SGM8304YTS14 100 MHz Quad Rail-to-Rail Op-Amp – Antminer S21
The SGM8304YTS14 is a quad high-voltage rail-to-rail output op-amp used on Antminer S21 hashboards for signal conditioning on the control / sense path. Unity-gain stable with 100 MHz bandwidth, the device delivers high-speed performance with stable, reliable output under varied load conditions.
Wide supply range (+4.5 V to +12 V single supply or ±2.25 V to ±6 V dual) and 103 mA output drive handle the demanding loads on miner hashboards. Low differential gain/phase (0.02 % / 0.02 °) preserves accurate signal reproduction across the analog chain.
Typical Use Cases
- Hashboard signal conditioning — sense / measurement / feedback amplification.
- Failed op-amp replacement — restore signal chain after a fault event.
- ADC interface buffering — drive ADC inputs cleanly with rail-to-rail output.
- Production refurbishment — bulk op-amp stock for S21 rework lines.
