The AD7294-2 is a highly integrated solution that offers all the functionality necessary for precise control of the power amplifier in cellular base station applications. In these types of applications, the DACs provide 12-bit resolution to control the bias currents of the power transistors. Thermal diode-based temperature sensors are incorporated to compensate for temperature effects. The ADC monitors the high-side current and temperature. This functionality is provided in a 64-lead TQFP, which operates over a temperature range of −40°C to +105°C.
APPLICATIONS
- Cellular base stations
GSM, EDGE, UMTS, CDMA, TD-SCDMA, W-CDMA, WiMAXM - Point-to-multipoint and other RF transmission systems
- 12 V, 24 V, 48 V automotive applications
- Industrial controls
