Dear anyone,
I want to complete the PA(eg. RF5110) gain controlling. The voltage range of power control pin Vapc is 0-2.8V. Please refer to the attachment for detailed input characteristics. Which simple chip can be used to realize that the 3.3V or 5V power supply is converted to the Vapc requirements 0-2.8V? The best is a programmable chip. Can anybody recommand one? It's urgent.
Thanks.
