Overview
The ADUM3195WBRQZ is an automotive-qualified isolated amplifier based on iCoupler technology, featuring adjustable gain and single-ended output. It operates within a supply voltage range of 4.5 V to 5.5 V for both sides. The device provides a 210 kHz bandwidth and 3000 Vrms isolation rating. Key electrical parameters include a maximum input offset voltage of 1.5 mV, a gain-bandwidth product of 15 MHz, and an operating temperature range from -40°C to +125°C. It includes two high-accuracy 2.5 V reference outputs.
Feature Summary
- High-impedance input suitable for isolated voltage measurement applications
- Low offset error and drift ensuring stable transfer functions over lifetime
- Integrated wideband operational amplifiers for loop compensation
- Two high-accuracy 2.5 V reference outputs included
Applications
- Inverters
- DC to DC converters
- On-board chargers
Procurement Notes
Verify the W suffix indicates AEC-Q100 automotive qualification. Confirm the RQZ package designation corresponds to the 16-lead QSOP form factor. Ensure compatibility with the EVAL-ADUM3195EBZ evaluation board for performance validation. Check pending regulatory approvals status if safety certification is required for the specific deployment environment.
Selection Notes
Select this component for applications requiring high stability and low drift in isolated voltage sensing. The automotive qualification supports use in electric and hybrid vehicle systems. Consider the 210 kHz bandwidth and 3000 Vrms isolation when designing feedback loops for power supplies. Verify that the 4.5 V to 5.5 V supply requirement aligns with system power rails.
Part Context
The ADUM3195 series utilizes iCoupler technology to provide galvanic isolation without optocouplers. This eliminates current transfer ratio uncertainty associated with optical solutions. The family offers low offset and gain errors, making it ideal for precision isolated voltage sensing across wide temperature ranges.
Replacement Considerations
The ADUM3195BRQZ serves as the commercial equivalent. Both share identical specifications and pinouts. The primary distinction lies in the manufacturing controls and reliability reporting associated with the automotive-grade W suffix.
