LM321A-TR 21AMC Repair Whatsminer Control Board Chip - Restore Performance

The LM321A-TR amplifier is the ultimate solution for repairing non-working chips on Whatsminer control boards. With its cutting-edge technology and exceptional performance, it efficiently restores normal functionality. This high-supply voltage amplifier boasts low offset, low power consumption, and a stable frequency response.

LM321A-TR Amplifier - Low Power Consumption with Stable Frequency Response

Designed using 3PEAK's proprietary and patented technology, the LM321A-TR achieves remarkable AC performance with a bandwidth of 0.9MHz, a slew rate of 0.5V/μs, and a maximum offset of only 3mV. It operates with a mere 100μA quiescent current per amplifier, ensuring energy efficiency.

Key Features:

  • 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/μs
  • Excellent EMI suppression performance: 71dB at 1GHz
  • Offset voltage: +3mV max
  • Offset voltage temperature drift: 7μV/°C
  • Operating temperature range: -40℃ to 125℃

Application:

  • Whatsminer control board
  • Power module
  • Sensor interface
  • Motor control
