... The CS4341A is pin and functionally compatible with all CS4341 designs, operating at the standard audio sample rates, that use pin serial clock input. In addition to the features of the CS4341, the CS4341A supports standard sample rates up to 192 kHz, as well as automatic mode detection for sample rates be- tween 4 and 200 kHz ...

... Grounding and Power Supply Arrangements As with any high resolution converter, the CS4341A requires careful attention to power supply and grounding arrangements if its potential performance realized. Figure 1 shows the recommended power arrangements, with VA connected to a clean supply. If the ground planes are split between digital ground and analog ground, REF_GND & ...

... When excess capacitive loading is present on the I sufficient hysteresis to meet the standard I 2 mon I C configurations with a resistor pull-up. A workaround is achieved by placing a Schmitt Trigger buffer, a 74HC14 for example, on the SCL line just prior to the CS4341A. This will not affect the operation of the 3.9.2 MAP Auto Increment The device has MAP (memory address pointer) auto increment capability enabled by the INCR bit (also the MSB) of the MAP ...
