ft6203 The ft6203 family is 1.25W mono fully differential audio power amplifier designed for driving a speaker of 8Ω impedance or above with optimized PCB area consumption. The ft6203 can operate from 2.5Vto 5.5V, drawing only 1.9mA of quiescent supply current. Available packages include 3mm x 3mm DFN and 3mm x 4.8mm MSOP packages. The ft6203 provides multiple features including 85dB PSRR from 90Hz to 5Hz, improved RF-rectification immunity and the optimized PCB consumption which altogether build up an ideal solution for mobile phones, PDAs or other handheld devices.
