EVAL-AD1852EB

The EVAL-AD1852-EB evaluation board permits testing and demonstrating the high-performance AD1852 24-bit stereo DAC. An input signal is required in either optical or coaxial SPDIF format or, alternatively, directly via a 10-pin header in I2S, left justified, right justified, or DSP modes. A second 10-pin header and DB-9 connector allows control of the internal registers from an external SPI controller.

Power requirements are a clean 9 V to 12 V dc source for the digital section and a clean ±12 V dc for the analog section. The positive supplies can be paralleled if desired. On-board regulators derive EVAL-AD1852-EB separate "clean" 5 V dc supplies for the digital and analog sections. Audio output is provided from two RCA phono jacks.
