CS42L52-CNZ

The CS42L52-CNZ is a type of highly combined, low-power stereo CODEC with headphone and Class D speaker amp lifiers. The ADC input path accepts independent channel control of a number of features. Input summing amplifiers mi x and select line-level and/or microphone-level inputs for each channel.The microphone input path contains a select able programmable-gain pre-amplifier stage and a low-noise MIC bias voltage supply. A PGA is usable for line or micr ophone inputs and offers analog gain with soft-ramp and zero-cross transitions.These features make it ideal for low-power, portable system applications.

Features of the  CS42L52-CNZ are:(1)12, 24, and 27 MHz master clock support in addition to typical audio clock rate s;(2) high-performance 24-bit converters:multi-bit delta-sigma architecture,very low 64Fs oversampling clock reduces power consumption;(3) low-power operation:stereo analog passthrough: 10 mW @ 1.8 V,stereo playback: 14 mW @ 1.8 V,stereo rec. and playback: 23 mW @ 1.8 V;(4) power-down management:ADC, DAC, CODEC, MIC pre-amplifier, pga,headphone amplifier, speaker amplifier;(5) headphone/speaker detection input;(6)pop and click suppression.

The absolute maximum ratings of the CS42L52-CNZ can be summarized as:(1):DC power supply(analog) is-0.3V min and 3.0V max,DC power supply(speaker) is-0.3V min and 6.0V max,DC power supply(digital) is-0.3V min and 3.0V max;(2):input current is ±10 mA max;(3):external voltage applied to analog input is AGND-0.3V min and VA+0.3 V m ax;(4):external voltage applied to analog output is VHP - 0.3V min and  VHP + 0.3 V max; (5):external voltage applie d to digital input is -0.3V min and  VL+ 0.3 V max;(6):ambient operating temperature (power applied) is -50°C min and +115 °C max;(7):storage temperature is -65°C min and +150°C max.
