Amplifiers

Current SenseQuad-ChannelBidirectionalTI

The INA4181A1IPWR is a high-precision, quad-channel bidirectional current sense amplifier from Texas Instruments, optimized for cost-sensitive applications requiring monitoring of up to four current rails.

Best for

  • Multi-rail current monitoring
  • Motor control
  • Battery management systems

Avoid if

  • Single-channel monitoring is sufficient (use INA181 instead)
  • Programmable gain is required

Check before use

  • Ensure shunt resistor power dissipation is within limits
  • Verify common-mode voltage does not exceed 26V
