28-Lead TSSOP/28-Lead SOIC GENERAL DESCRIPTION This monolithic 3 V CMOS device is a low power, two-channel,
input port with signal conditioning. 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 …
