Product Summary
The AD7729ARUZ is a low power, two-channel, input port with signal conditioning monolithic 3 V CMOS device. The receive path is composed of two high performance sigma-delta ADCs with digital filtering. A common bandgap reference feeds the ADCs. A control DAC is included for such functions as AFC. The auxiliary functions can be accessed via the auxiliary port (ASPORT). This device is available in a 28-lead TSSOP package or a 28-lead SOIC package. The applications of the AD7729ARUZ incldue GSM Basestations, Pagers.
