What are the key features of XOPA462IDDA?
- 180 V absolute maximum voltage rating enables direct interfacing to high-voltage rails in industrial and motor-drive signal conditioning without external protection networks
- 6.5 MHz bandwidth combined with 25 V/µs slew rate supports fast analog signal processing on high-voltage nodes such as current-sense and feedback in power converters
- 116 dB minimum CMRR and current-feedback architecture deliver precision differential measurement accuracy in the presence of large common-mode voltages up to the supply rails
What is XOPA462IDDA used for?
The XOPA462IDDA is suited for high-voltage signal conditioning in industrial motor drives, PLC analog input modules, and power-supply feedback loops where the signal path must tolerate supply rails well above 12 V. Its 6.5 MHz bandwidth enables precision measurement of current-sense signals at switching converter frequencies from tens of kilohertz up to several hundred kilohertz. Designers use this op-amp in isolation amplifier driver stages and high-side current monitors where input common-mode voltage can reach 100 V or more.

Frequently Asked Questions
Which industrial measurement scenarios require the 180 V rating of the XOPA462IDDA rather than a standard 36 V op-amp?
Applications involving direct measurement of voltages on 48 V, 72 V, or 100 V DC bus rails — such as high-voltage motor drives, battery management systems, or industrial PLC analog inputs — require an op-amp rated above those rail voltages. The XOPA462IDDA's 180 V absolute maximum rating allows it to sense signals referenced to high-voltage nodes without clamp diodes or voltage dividers that would increase noise and reduce accuracy, preserving the full 116 dB CMRR for precise differential measurements.
How does the 25 V/µs slew rate of the XOPA462IDDA affect its performance in switch-mode power-supply feedback loops?
At 25 V/µs slew rate, the XOPA462IDDA can slew a 10 V step in 400 ns, fast enough to track error signals in power supplies switching at 200 kHz to 500 kHz without introducing slew-limiting distortion in the feedback path. Combined with the 6.5 MHz small-signal bandwidth, this allows the compensation network to be designed for loop crossover frequencies up to 100 kHz, enabling tighter output regulation and faster transient response in high-frequency DC-DC and AC-DC converters.
For a high-voltage analog input card, what is the input offset voltage specification of the XOPA462IDDA and how does it affect measurement accuracy?
The XOPA462IDDA has a maximum input offset voltage of 4000 µV (4 mV), which at a 10-bit ADC with 100 V full-scale input represents approximately 0.04% of full scale — adequate for industrial process measurements requiring better than 1% accuracy. For higher-precision applications, an external trimmer or a 16-bit ADC with offset calibration in firmware can reduce the effective offset contribution, while the 120 dB typical CMRR ensures that common-mode voltages up to the supply rail do not significantly degrade differential measurement accuracy.
