DESCRIPTION This data sheet describes the evaluation board for the AD7294, which is a 12-bit monitoring and control device with multichannel ADC, DACs, temperature sensors, and current sensors. The AD7294 is a highly integrated solution that offers all the func-tionality necessary for precise control of the power amplifier in cellular base station applications. The AD7294 includes low voltage ( 200 mV) analog input sense amplifiers for current monitoring across shunt resistors, temperature sense inputs, and four uncommitted analog input channels multiplexed into a successive approximation (SAR) analog-to-digital converter (ADC) with a 3 s conversion time. A high accuracy internal reference is provided to drive both the digital-to-analog converter (DAC) and the ADC. Four 12-bit DACs provide the outputs for voltage control. The AD7294 also includes limit registers for alarm functions. The part is designed on the Analog Devices, Inc., high voltage diffused metal-oxide semiconductor (DMOS) FEATURES Full featured evaluation board for AD7294 Graphical user interface software with USB control Can be powered entirely from the USB port or using an external power source Various link options APPLICATIONS Cellular base stations (GSM, EDGE, UMTS, CDMA) Point-to-multipoint and other RF transmission systems 12 V, 24 V, 48 V automotive applications Industrial control GENERAL DESCRIPTION This data sheet describes the evaluation board for the AD7294, which is a 12-bit monitoring and control device with multichannel ADC, DACs, temperature sensors, and current sensors.
