The MAX4473EUA-T is a PA power control IC from Analog Devices, optimized for closed-loop bias control of GSM power amplifiers. It facilitates accurate control of current delivered to the power amplifier through a control voltage. The device operates from a single 2.7V to 6.5V supply and typically draws 1.2mA of supply current. In shutdown mode, the supply current is reduced to less than 1µA.
Key features include guaranteed 1.5µs enable/disable times, active output pull-down in shutdown mode, and rail-to-rail error amplifier output. The power control input also swings rail-to-rail. The error amplifier has a common-mode range from 1V to VCC. User-selectable current sensing and gain setting resistors maximize flexibility.
This IC is available in a space-saving 8-pin µMAX package, making it suitable for compact designs. Its design is particularly useful in time-division-multiple-access (TDMA) systems, such as GSM, where accurate transmit burst shaping and power control are required. Applications include GSM cellular phones, cordless phones, precision current control, and high-frequency servo loops.
