Key Features of ACS724LLCTR-10AB-T Current Sensor IC
Power electronics designers and automation engineers adopt ACS724LLCTR-10AB-T for its superior isolation, low loss and stable measurement accuracy:
- ±10 A bidirectional current sensing range with 200 mV/A sensitivity at 5 V supply
- 2400 Vrms galvanic isolation between primary current path and signal circuit for safety compliance
- Ultra-low 1.2 mΩ internal primary conductor resistance to minimize power dissipation and heat generation
- Differential Hall sensing architecture that suppresses external common-mode magnetic interference
- Integrated internal shielding eliminates capacitive coupling noise from high dv/dt switching transients
- 120 kHz high bandwidth analog output with fast response for real-time current loop control
- Dedicated filter pin for users to adjust bandwidth, optimizing measurement resolution at low frequencies
- Built-in digital temperature compensation delivers consistent accuracy across full operating temperature
- Chopper-stabilized circuit achieves near-zero magnetic hysteresis and stable quiescent output voltage
- Single 4.5 V–5.5 V supply voltage, ratiometric analog output centered at 2.5 V under zero current
- Fully factory-calibrated sensitivity and offset voltage to reduce system calibration workload
- Compact low-profile SOIC8 surface mount package, tape-and-reel (TR) packaging format
- Wide operating temperature range: -40°C to +150°C for high-temperature power equipment environments
- RoHS-compliant matte tin lead frame, compatible with standard SMT mass production processes
