The AD7293 is a PA drain current controller containing functionality for general-purpose monitoring and control of current, voltage, and temperature, integrated into a single chip solution with an SPI-compatible interface.The device features a 4-channel, 12-bit successive approximation register (SAR) ADC, eight 12-bit DACs (four bipolar and four unipolar with output ranges that can be configured to shut down under external pin control), a ?1.25?C accurate internal temperature sensor, and eight general-purpose input/output (GPIO) pins.The device also includes limit registers for alert functions and four high-side current sense amplifiers to measure current across external shunt resistors. These amplifiers can be optionally set to operate as part of four independent closed-loop drain current controllers.A high accuracy 2.5 V internal reference is provided to drive theDACs and the ADC. The 12-bit ADC monitors and digitizes theinternal temperature sensor, and two inputs are included for theexternal diode temperature sensors.Product Highlights Four independent closed-loop drain current controllers. Built-in monitoring, sequencing, and alert features. Compatible with both depletion mode and enhancement mode power amplifiers.Applications GaN and GaAs power amplifier monitoring and controls Base station power amplifiers General-purpose system monitoring and controls
