Description

The ISO122U is a high-performance isolation amplifier developed by Texas Instruments, designed to offer reliable and precise voltage isolation. With its state-of-the-art technology, the ISO122U ensures that signals are transmitted accurately across a galvanic isolation barrier, making it an ideal choice for critical applications in industrial, medical, and other systems where isolation is a necessity.

Key Features

  • High Accuracy: The ISO122U boasts a low nonlinearity of 0.01% max at G = 100, ensuring high precision in signal amplification.
  • High Isolation Voltage: It offers a 1500Vrms of isolation voltage, providing a robust barrier against high voltage spikes and surges.
  • Low Offset Voltage: A low offset voltage of 50µV max and low offset drift of 0.5µV/°C max contribute to the amplifier's stable performance over temperature variations.
  • Bipolar Operation: The device supports a wide input signal range, making it suitable for both unipolar and bipolar input signals.
  • High Bandwidth: With a bandwidth of up to 100kHz, the ISO122U can handle a broad range of signal frequencies without compromising the integrity of the signal.
  • Robust Packaging: Available in an 8-pin plastic DIP and 16-pin SOIC, the ISO122U is designed for easy integration into a variety of circuit designs.
  • Single Supply Operation: It can operate from a single +4.5V to +36V power supply or a dual ±4.5V to ±18V power supply, providing flexibility in power design.

Applications

The ISO122U is versatile and can be deployed in numerous applications that require accurate signal isolation, such as:

  • Data acquisition systems
  • Ground loop elimination
  • Industrial process controls
  • Test equipment
  • Motor control feedback systems
  • Medical equipment

With its exceptional performance and reliability, the ISO122U from Texas Instruments stands out as a premier solution for designers looking to maintain signal integrity across isolated interfaces.
