Product overview
Overview
The MAX4473 PA power control IC is intended for closed-loop bias control of GSM power amplifiers.
The device facilitates accurate control of the current delivered to the power amplifier (PA) via a control voltage.
The error amplifier senses the voltage drop across an external current-sense resistor placed between the supply and the PA.
The output of the error amplifier adjusts the PA gain until the current is proportional to the power control voltage applied to the MAX4473. This unique topology is useful in time-division-multiple-access (TDMA) systems, such as GSM, where accurate transmit burst shaping and power control is required.User-selectable current sensing and gain setting resistors maximize flexibility.
The MAX4473 operates from a single +2.7V to +6.5V supply and typically draws 1.2mA of supply current.
The error amplifier has a common-mode range that extends from +1V to VCC.
The power control input and error amplifier outputs swing Rail-to-Rail®. A low-power shutdown mode reduces supply current to less than 1µA and activates an on-board active pull-down at the error amplifier output. Fast enable/disable times of 0.9µs reduce average power consumption without compromising dynamic performance.
The MAX4473 is available in a space-saving 8-pin µMAX package.
