Current Monitoring

INA901-SP is a high-precision current sense amplifier that is both radiation-hardened and space-qualified. It supports a wide common-mode input range up to 65 V, making it suitable for various system voltages. Its optimized bandwidth ensures fast detection of overcurrent events, while high power-supply rejection and fast settling times help avoid false alarms caused by transient noise or interference. This enables high sensitivity and accuracy without compromising availability.
