The AD2S44 is a low-cost, 14-bit, dual channel synchro/resolver-to-digital converter. It is designed specifically for applications where space, weight, and cost are at a premium. Each 32-lead hybrid device contains two independent Type II servo loop tracking converters.
The AD2S44 is a 14-bit dual channel, continuous tracking synchro/resolver-to-digital converter designed specifically for applications where space, weight, and cost are at a premium. Each 32-lead hybrid device contains two independent Type II servo loop tracking converters. The ratio metric conversion technique employed provides excellent noise immunity and tolerance of long lead lengths.
The core of each conversion is performed by state-of-the-art monolithic, integrated circuits manufactured by the Analog Devices, Inc., proprietary BiMOS II process, which combines the advantages of low power CMOS digital logic with bipolar linear circuits. The built-in test (BIT) facility can be used in fail-safe systems to provide an indication of whether the converter is tracking accurately.
