    Small Volume I/F Conversion Circuit

    Introduction

    ER-IFC-G10M is a high-precision current/frequency conversion circuit using charge integration. This conversion circuit can continuously convert the current signals output by three accelerometers at the same time. The three accelerometers work independently without any influence on each other. It has the characteristics of small volume, high output frequency and high precision.
