Diodes Incorporated has introduced an 8 channel DAC and pre-amplifier chip. Part of the Zetex Direct Digital Feedback Amplifier (DDFA) product line, the ZXCZM800 will reduce circuit complexity, and in high performance differential mode, will deliver a dynamic range (DNR) as high as 126db. In terms of DAC performance metrics, the ZXCZM800 offers a maximum resolution of 32 bits. Maximum sample rate is up to 192kHz and DNR in single ended operating mode is 120dB. For distortion and noise, figures less than 0.001% are typical for single ended mode, less than 0.0004% in differential mode. The ZXCZM800 DAC and pre-amplifier chip is supported by an 8-channel demonstration board, details of which will be made available for volume production DAC and preamplifier designs, and includes circuit diagrams, bill of materials and Gerber files.
