The Allegro fully-integrated current sensor IC package allows for easy implementation. The fully-differential output of this device gives better immunity to output offset drift as well as common mode noise.
ACS726 is the first current sensor to include a fully-differential back-end amplifier that can be used to adjust gain and bandwidth via external RC networks. The back-end amplifier is fully independent and when unused, it can be powered down to reduce power consumption.
Features and Benefits |
|
|
- Fully-differential architecture for immunity to output offset drift and common mode noise
- Spare differential back-end amplifier for externally adjustable gain and bandwidth using simple RC networks
- High-bandwidth 120 kHz analog output
- 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 V 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
- Nearly-zero magnetic hysteresis
- Ratiometric output supply voltage
