SY2A55104/SY2A55105 High-Side or Low-Side Bidirectional, High-Accuracy, Current-Sense Amplifier General Description The SY2A55104 and SY2A55105 fixed-gain, highprecision, high-side or low-side, current-sense amplifiers with voltage output are suitable for bidirectional (charge /discharge) or unidirectional current measurements. The SY2A55104 provides 50V/V output gain and the SY2A55105 provides 100V/V output gain. The SY2A55104/5 use a low-offset, zero-drift architecture and operate across the -0.3V to 26V input mon-mode voltage range, which is independent of supply voltage. The precision input offset voltage (VOS) allows the devices to measure the low-voltage drop very accurately. The SY2A55104/5 are designed to operate from a 3V to 5.5V supply and draw just 80µA (typ) quiescent current. The devices are provided in an SOT363 package and are specified over the extended industrial temperature range of -40°C to 125°C. The device is AEC- Q100 Qualified.
