Telegram : @zeusmining_presalesLM321A-TR for Whatsminer control board replacement chip
The LM321A-TR amplifier is the latest high-supply voltage amplifier with low offset, low power consumption, and stable frequency response. It is often used to repair non-working chips on Whatsminer control boards to help restore normal performance. They utilize 3PEAK's proprietary and patented design technology to achieve very good AC performance with 0.9MHz bandwidth, 0.5V/μs slew rate, and 3mV maximum offset while consuming only 100μA quiescent current per amplifier. The input common-mode voltage range extends to V–, and the output swings rail-to-rail. The LM321A-TR can be used as a plug-in replacement for many commercial op amps to reduce power consumption and increase input/output range and performance.
Feature:
• Supply voltage: 3V to 36V
• Low supply current: 100μA per channel
• Input common-mode voltage range includes ground
• Rail-to-rail output
• Bandwidth: 0.9 MHz
• Slew rate: 0.5V/us
• Excellent EMl suppression performance: 71dB at 1GHz
• Offset voltage: +3mV max
• Offset voltage temperature drift: 7 yV/C
• -40℃ to 125℃ operating temperature range
Application:
• Whatsminer control board
• Power module
• Sensor interface
• Motor control
