6. Product overview
6.1. Overview
The TLP7820 is an optically coupled isolation amplifier that has a high-precision delta-sigma AD
converter at the primary side and a DA converter at the secondary side.

Recommended supply voltage ranges:
Primary side = 4.5 to 5.5 V, Secondary side = 3.0 to 5.5 V

Operating temperature range: -40 to +105°C

Common-mode transient immunity (CMTI): 15kV/μs (minimum)

Low power consumption:
Primary supply current = 8.6 mA (typical), Secondary supply current = 6.2 mA (typical)

Thin package (SO8L) contributes flexible PCB designs
