CS4461-CZZR集成電路（IC）的模數(shù)轉(zhuǎn)換器（ADC）規(guī)格書(shū)PDF中文資料

CS4461-CZZR屬于集成電路（IC）的模數(shù)轉(zhuǎn)換器（ADC）。由凌云邏輯制造生產(chǎn)的CS4461-CZZR模數(shù)轉(zhuǎn)換器（ADC）模數(shù)轉(zhuǎn)換器（ADC、A/D 或 A 轉(zhuǎn) D）對(duì)模擬信號(hào)進(jìn)行采樣，例如由麥克風(fēng)采集的聲音或傳感器的輸出，然后將其轉(zhuǎn)換為數(shù)字信號(hào)。一般來(lái)說(shuō)，數(shù)字輸出是二進(jìn)制補(bǔ)碼二進(jìn)制數(shù)，與輸入成比例。輸入類型可能是差分、偽差分或單端輸入。模數(shù)轉(zhuǎn)換器可按照位數(shù)、采樣率、輸入數(shù)、接口、轉(zhuǎn)換器數(shù)和架構(gòu)（例如自適應(yīng)增量、雙斜率、折疊、流水線、SAR、三角積分、兩步式）進(jìn)行選擇。

General Description

The CS4461 is a complete analog-to-digital converter for class-D real-time power supply rejection (PSR) feedback. It performs sampling and analog-to-digital conversion, generating digital data for input to a class-D modulator with real-time PSR feedback capabilities.

Features

● Advanced Multi-bit Delta-Sigma Architecture

● Real-time Feedback of Power Supply Conditions (AC and DC)

● Filterless Digital Output Resulting in Very Low Signal Delay

● 135 mW Power Consumption

● Supports Logic Levels Between 3.3 V and 5.0 V

● Differential Analog Architecture

● Modulator Overflow Detection

● Interfaces Directly to the CS44800/CS44600 Class-D PWM Modulator

● Multi-bit Conversion at up to 7.5 MHz

● Delivers Modulated Data Over 2-Wire Interface
