20VS5-210

Hybrid IC Isolation Amplifiers 20 Series

ISOLATION AMPLIFIER

(high-accuracy, input isolation, external synchronous)
Functions & Features
• Being used for printed wiring board installation
• Up to 1500 V isolation between input to output or power input
• High-linearity
• Small installation area in printed wiring board
• Gain adjustable range, × 1 to × 100
• Powered with external Clock Generator (model: 20VS5-2)
Typical Applications
• Isolating the field and input circuit of microprocessor to reduce noise from field
• Available for manufacturers of small-lot products to omit the development of isolation circuit
• Using external Clock Generator to eliminate the "beat frequency" interference at multi-channel outputs.
