Power D/A converter using the AD7520.The Intersil AD7520 is an 18-pin multiplying DIA converter. This circuit is designed for 8-bit accuracy and 10-bit resolution.The Intersil IH8510 power amplifier(1A continuous output) is driven by the AD7520.A summing amplifier between the AD7520 and IH8510 is used to separate the gain block containing the AD7520 on-chip resistors from the power amplifier stage,whose gain is set only by the external resistors.This approach minimizes drift, otherwise the AD7520 can be directly connected to the IH8510 by using a 25-volt reference for the D/A converter(courtesy Intersil, Inc.).
