DESCRIPTION
The PCM1750 is a low cost, dual 18-bit CMOS analog-to-digital converter optimized for dynamic signal applications. The PCM1750 features true co-phased inputs with an internal sample/hold function for each channel. The PCM1750 also es plete with an internal reference. Total power dissipation is less than 300m W max using ±5V voltage supplies. Low maximum Total Harmonic Distortion + Noise (- 88d B max) is 100% tested. The very fast PCM1750 is capable of 4X x audio bandwidth oversampling rates on both input channels simultaneously, providing greater freedom to designers in selecting input anti-aliasing...
