Unitrode UCC2926
The UCC3926 Current Sensor IC contains a wideband, transimpedance amplifier for converting the current through an internal, non-inductive 1.3mΩ shunt resistor into a proportional voltage. The sense element operates in both high-side (VDD referenced) and low-side (GND referenced) applications. The UCC3926 can measure currents up to ±20A.| Part No. | UCC2926 |

DESCRIPTION
The UCC3926 can measure currents up to ±20A. This transimpedance amplifier gain is precisely trimmed to 33.3mΩ to convert a 15A input into a 500mV output signal. It has a very low input offset voltage from chopper-stabilization. A cross-switching block rectifies the input signal by forcing the differential output, AOP positive with respect to the other differential output, AON. SIGN indicates the polarity of the current. The UCC3926 programmable amplifier provides three functions. It converts the differential transimpedance output signal into a single-ended signal.
