Frequently Asked Questions

What common-mode voltage range does the INA2180A2IDSGT support, and why does that matter for industrial applications?

The INA2180A2IDSGT supports a common-mode voltage range of up to 26 V, making it compatible with 12 V, 15 V, and 24 V industrial bus rails commonly used in motor drives and power converters. This wide range allows accurate current sensing even when the supply rail fluctuates or experiences transients without saturating the amplifier.

How does the 350 kHz bandwidth affect current sensing in switching power supply designs?

With a 350 kHz bandwidth, the INA2180A2IDSGT can track current waveforms in switching converters operating up to several hundred kilohertz switching frequencies, enabling fast overcurrent detection and control-loop feedback. Its voltage-feedback architecture with frequency compensation ensures stable gain response across that bandwidth, reducing loop instability in DC-DC converters.

Can the INA2180A2IDSGT operate in automotive-grade temperature environments?

The INA2180A2IDSGT is rated for -40°C to 125°C, covering the extended industrial temperature range used in automotive and harsh-environment equipment. Both channels maintain their 84 dB CMRR and 150 µV maximum offset across the full temperature range, ensuring consistent measurement accuracy in engine bay or underhood applications.

How does having two channels in one 8-pin WSON package benefit board space and BOM cost?

Integrating 2 independent current sense amplifier channels into a single 8-pin WSON package reduces PCB area by roughly 50% compared to using two discrete single-channel devices, while also cutting BOM line items. This dual-channel integration is particularly valuable in motor H-bridge designs that require monitoring current on two legs simultaneously within a tight layout.
