ADC, DACs, and Temperature and Current Sensors AD7293 Data Sheet APPLICATIONS
GaN and GaAs power amplifier monitoring and controls
Base station power amplifiers
General-purpose system monitoring and controls GENERAL DESCRIPTION
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. Rev. D PRECISION
