Compact HV Instrumentation Amplifier with a Reference Input.

Ratio of 63.5V input to 1V output, all resistors are 0.1% tolerance, total error is maximum of 1%.

Isolation between the input and the output sides is 1kV.

All inputs, output and power supply are EMI/EMC and ESD protected.

Common Mode Rejection Ratio (CMRR) is -50dB for max 500Vac with maximum frequency components of 100kHz.

Frequency responce to -3dB LPF is faily flat (less than +/-0.2dB) from DC to 100kHz.

Power Supply 2.5V to 5.5V, switable for 3.3V and 5.0V acquisition systems.

VREF input has rail to rail voltage acceptance, this allows for DC and AC measurements.

All pins are positioned on 0.1" grid switable for prototype boards and solderless breadboards.

Overal size of the body is 32x14x5.5mm excluding pins. Pins length is 7.62mm (0.3").

Ideal for applications like BMS, Inverter, Solar, PLC, Data Acquisition and IoT.

For 3.3V ADC input the measurements can be 200Vdc (VREF tied to 0V) or 100Vac (VREF tied to VCC/2).

For 5.0V ADC input the measurements can be 310Vdc (VREF tied to 0V) or 155Vac (VREF tied to VCC/2).

Please do let me know if you would like to have any other input to output ratio so I can give you a quote, lead time and simulated parameters of the desired part.

Please let me know if you have any questions about this item.

I use Royal Mail 1st Class Tracked for all deliveries.
