SY2A55105 Datasheet Current-sense Amplifier

Manufacturer: Silergy

Overview: SY2A55104/SY2A55105 High-Side or Low-Side Bidirectional, High-Accuracy, Current-Sense Amplifier.

This datasheet includes multiple variants, all published together in a single manufacturer document.

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.
