ACPL-C87BT-000E
Overview
The ACPL-C87BT-000E is an automotive-grade precision isolation amplifier designed for voltage sensing in high-power environments. It features a high common-mode rejection of 15 kV/microsecond and a 100 kHz bandwidth, making it suitable for monitoring DC-link voltages and phase currents in electric vehicle systems. The device operates across a wide temperature range of -40 to 125 degrees Celsius and includes an active-high shutdown feature for power-sensitive applications.
Why Choose This Part
This amplifier offers excellent precision with 0.5 percent accuracy and a low input offset voltage of 300 uV. It is AEC-Q100 Grade 1 qualified and meets stringent safety standards including UL 1577 and IEC/EN/DIN EN 60747-5-5, providing a working voltage of 1414 Vpeak in a space-saving stretched SO-8 package.
Applications
Key Specifications
Getting Started
Designers should ensure proper PCB creepage and clearance distances are maintained under the stretched SO-8 package to meet isolation ratings. The device requires a 5V supply on both the input and output sides; use a low-noise isolated DC-DC converter for the primary side supply. Evaluate performance using a differential-to-single-ended op-amp circuit on the output to interface with standard MCU ADCs.
