GP8102-F50-NH-SW

GP8102 is a PWM-to-analog signal converter, functionally equivalent to a DAC with PWM signal input and analog signal output. The device achieves an output current error of less than 0.5%.

Applications

• Motor speed control
• LED dimming
• Inverter
• Power supply
• Industrial analog signal isolation

Key features

• Linearly converts PWM input signals with duty cycles from 0% to 100% into current signal outputs. By selecting an appropriate sampling resistor (e.g., Rs=250Ω), an analog current output range of 0-20mA can be achieved; the output current range is adjustable by changing Rs.
• Output current formula: IOUT = DPWM × 5V / Rs, where DPWM is the high-level duty cycle of the input PWM signal and Rs is the sampling resistor.
• Input PWM signal frequency range: 50Hz to 50KHz (contact the manufacturer if frequency is below 50Hz).
• Input PWM signal high-level voltage range: 2.7V-5.5V.
• Output voltage error: < 1% (typical: 0.5%, 0.1%).
• Output voltage linearity error: < 0.5% (typical: 0.2%, 0.1%).
• Supply voltage range: 9V - 36V.
• Quiescent current: < 2mA.
• Startup time: < 2ms.
• Operating temperature range: -40℃ to 85℃.
