TLP78x/TLP79x Isolation Amplifiers

Toshiba TLP78x/TLP79x Optically Coupled Isolation Amplifiers feature input side Sigma-Delta (∑-Δ) analog-to-digital converter technology (ADC). The ADC converts analog input signals into high-speed digital data streams with galvanic isolation based on optical coupling technology. This enables these devices to achieve a high level of linearity. TLP78x and TLP79x provide a guaranteed Common Mode Transient Immunity of 20kV/µs (typical @VCM=1kV, Ta=25°C). The optical barrier guarantees an isolation voltage of 5000Vrms (minimum). These Toshiba amplifiers offer extremely stable operation, even in electrically noisy environments, making them ideal for motor control applications.
