High Output Frequency I/F Conversion Circuit

ER-IFC-G10 Features
High-precision current/frequency conversion circuit
Convert current signals output by three accelerometers

Product Details

1.General Introduction

ER-IFC-G10 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 channels work independently without mutual influence.It has the characteristics of small volume, high output frequency and high precision.
