The PCM1604(1) and PCM1605(1) are CMOS mono-lithic integrated circuits which feature six 24-bit audio digital-to-analog converters, and support circuitry in a small QFP-48 package. The digital-to-analog convert-ers utilize Burr-Brown's enhanced multi-level, delta-sigma architecture, which employs 4th-order noise shaping and 8-level amplitude quantization to achieve excellent signal-to-noise performance, and a high tol-erance to clock jitter.
The PCM1604 and PCM1605 accept industry-stan-dard audio data formats with 16- to 24-bit audio data.
Sampling rates up to 200kHz are supported. A full set of user-programmable functions are accessible through a 4-wire serial control port which supports register write and readback functions.
NOTE: (1) The PCM1604 and PCM1605 utilize the same die and are electrically identical. All references to the PCM1604 apply equally to the PCM1605. NOTE: (1) The PCM1604 and PCM1605 utilize the same die and are electrically identical. All references to the PCM1604 apply equally to the PCM1605.
