ISO124U Description

Short technical summary and product information.

The ISO124U from Texas Instruments is a precision isolation amplifier that utilizes a duty cycle modulation-demodulation technique for reliable signal transmission across a capacitive barrier. This design ensures excellent reliability and immunity to high-frequency transients.

Key electrical specifications include a ±10-V input range, a wide supply voltage range of ±4.5 V to ±18 V, and a signal bandwidth of 50 kHz. The amplifier boasts a maximum nonlinearity of 0.010% and a low Vos drift of 200 µV/°C. It is rated for high-voltage breakdown up to 1500 Vrms and offers a high common-mode rejection ratio (CMR) of 140 dB at 60 Hz.

Designed for ease of use, the ISO124U requires no external components for operation and is available in a 16-pin PDIP and a 28-lead SOIC plastic surface-mount package. The operating temperature range is -25°C to 85°C.

This isolation amplifier is suitable for various applications requiring precise voltage sensing in isolated environments.
