The SY2A55105 fixed-gain, high-precision, high-side or low-side, current-sense amplifiers with voltage output are suitable for bidirectional (charge /discharge) or unidirectional current measurements. The SY2A55105 provides 100V/V output gain.
The SY2A55105 uses a low-offset, zero-drift architecture and operate across the -0.3V to 26V input common-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 SY2A55105 is designed to operate from a 3V to 5.5V supply and draw just 80µA (typ) quiescent current.
The device is provided in an SOT363 package and is specified over the extended industrial temperature range of -40°C to 125°C. The device is AEC−Q100 Qualified.
