Current-Sensor-ICs
Galvanically Isolated Current Sensor IC With Differential Output and Externally Adjustable Gain
ACS726
These parts are in production but have been determined to be LAST TIME BUY. The ACS726 is a precise AC current sensor IC with a fully differential output for noise immunity and an adjustable back-end amplifier. It features a low-offset Hall sensor with a 1.1mΩ copper conduction path and electrical isolation, enabling high-side current sensing with low power loss.

Top Features
- Fully differential architecture for improved immunity to offset drift and common mode noise
- Spare differential back end amplifier for externally adjustable gain and bandwidth using simple RC networks
- Greatly improved bandwidth through proprietary amplifier and filter design techniques
- High bandwidth 120 kHz analog output
- Patented integrated digital temperature compensation circuitry allows nearly closed-loop accuracy, through entire temperature range, in an open loop sensor
- 1.1 mΩ primary conductor resistance for low power loss and high inrush current withstanding capability
- Small footprint, low-profile QSOP24 package suitable for space-constrained applications
- Integrated shield virtually eliminates capacitive coupling from current conductor to die due to high dV/dt voltage transients
- 3 to 3.6 V, single supply operation
- Factory-trimmed sensitivity and quiescent output voltage for improved accuracy
- Chopper stabilization results in extremely stable quiescent output voltage
- Ratiometric output from supply voltage
