SY24641
SY24641 is Current-Sense Amplifier manufactured by Silergy.
SY24641/SY24642
High-Side or Low-Side Bidirectional, High-Accuracy, Current-Sense Amplifier
General Description
The SY24641 and SY24642 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 SY24641 provides 50V/V output gain and the SY24642 provides 100V/V output gain.
The SY24641/2 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 SY24641/2 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.
