GP210-MH

GP210 is a DAC with a PWM digital interface, capable of linearly converting PWM voltage to a 0–20mA or 4–20mA analog current output. The output range can be configured via an external resistor Rset. Initial analog output error is less than 0.1%, and output current linearity error is less than 0.05% (with two-point calibration). This product is designed for sensors, instrumentation, and industrial control applications with demanding performance requirements, addressing diverse output needs.
