Isolated amplifiers
High-performance isolated amplifiers for high-voltage systems
Isolated current and voltage sensing amplifiers
Increase system accuracy and reduce board space with our integrated high-voltage resistors
Our isolated integrated high-voltage resistors integrate the high-voltage resistor ladder and isolated amp into one package.
Benefits:
? Low temperature and lifetime drift compared to discrete resistors, enabling voltage measurements with accuracy errors <1% without the calibration external resistors require.
? Removing need for up to 15 external high-voltage resistors lowers system-level costs and reduces solution size by up to 50%.
??High-voltage resistor ratios for industry standard voltage levels such as ±400VAC and 600V/1000VDC.
??Single-ended ratiometric output for reducing BOM and solution cost and differential output for greater noise immunity.
? Lower manufacturing time and costs by eliminating the need for system-level calibration.

Eliminate the need for an external high-side supply with our single-supply isolated converters
Our isolated single-supply devices integrate an DC/DC converter that enables single-supply operation from the low side of the device.
Benefits:
? Measuring non-ground-referenced signals such as phase-to-phase measurements creates a novel solution for noisy, space-constrained applications.
? Removing the external high-side supply helps simplify designs and reduce board space and cost.
Solutions for both isolated voltage sensing and isolated shunt-based current sensing.

Remove the need for external components by directly interfacing with your MCU
Our isolated voltage-sensing devices have two single-ended output options: fixed gain and ratiometric (variable) gain.
Benefits:
? Fixed-gain and ratiometric single-ended output devices integrate the differential to single-ended operational amplifier, reducing solution size and system costs and enabling direct interfacing with the microcontroller (MCU).
? Ratiometric single-ended output devices can vary the output swing of the isolated voltage-sensing amplifier to match the full scale range of the analog-to-digital converter (ADC) inside the MCU, increasing measurement resolution and allowing for the full use of the ADC's dynamic range.
Solutions for both isolated voltage sensing and isolated shunt-based current sensing.
