Vishay ISO-DC-VSAO Isolated DC Voltage Reference Design
Vishay ISO-DC-VSAO Isolated DC Voltage Reference Design is based on the VIA2000SD isolation amplifier and a CDHV voltage divider. This solution is used in high DC-voltage applications where an isolated high-voltage sensing circuit is required. The high input voltage is scaled down to +2000mV using a set of CDHV resistors, which is then fed into the VIA2000SD isolation amplifier, producing an isolated, amplified analog signal at its output. Pin headers labeled OUTP and OUTN make the differential output signal accessible, allowing users to connect a differential ADC or to use it for other prototyping needs. Additional features include an isolated single-ended analog output, a low temperature offset and GAIN drift, and a large bandwidth of 290kHz. Vishay ISO-DC-VSAO Isolated DC Voltage Reference Design is ideal for power supplies, battery monitoring systems, EV powertrains, and motor control applications.
