7、nvertersand support circuitry in a small 16-lead SSOP package.The data converters use TIs enhanced multileveldelta-sigma architecture, which employs 4th-order noiseshaping and 8-level amplitude quantization to achieveexcellent dynamic performance and improved tolerance toclock jitter. The PCM1753/54
8、/55 accepts industry-standard audio data formats with 16- to 24-bit data,providing easy interfacing to audio DSP and decoderchips. Sampling rates up to 200 kHz are supported. A fullset of user-programmable functions is accessible througha three-wire serial control port, which supports registerwrite
9、functions.The PCM1753/55 is pin compatible with the PCM1748,PCM1742, and PCM1741, except for pin 5.These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam duringstorage or handling to prevent electrostatic damage to the MOS gat
