GP9301B-F1K-D5V9-SW

GP9301B is an analog-to-PWM signal converter, functionally equivalent to an ADC with PWM output. The device linearly converts a 0V to 10V analog voltage into a PWM signal with a duty cycle ranging from 0% to 100%, with a duty cycle linearity error of less than 0.5%. It also supports 100K resistor and PWM signal inputs. GP9301BM is a capacitive isolation-enabled variant.

Applications

• DC motor speed control
• LED dimming
• Industrial analog signal isolation
• Inverter
