AD7366屬于集成電路（IC）的模數(shù)轉換器（ADC）。由亞德諾半導體技術有限公司制造生產的AD7366模數(shù)轉換器（ADC）模數(shù)轉換器（ADC、A/D 或 A 轉 D）對模擬信號進行采樣，例如由麥克風采集的聲音或傳感器的輸出，然后將其轉換為數(shù)字信號。一般來說，數(shù)字輸出是二進制補碼二進制數(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)轉換器可按照位數(shù)、采樣率、輸入數(shù)、接口、轉換器數(shù)和架構（例如自適應增量、雙斜率、折疊、流水線、SAR、三角積分、兩步式）進行選擇。

GENERAL DESCRIPTION

The AD73661 is a dual, 12-bit, high speed, low power, successive approximation ADC that features throughput rates up to 1 MSPS. The device contains two ADCs, each preceded by a 2- channel multiplexer, and a low noise, wide bandwidth track and-hold amplifier that can handle input frequencies in excess of 10 MHz.

The AD7366 is fabricated on Analog Devices’ Industrial CMOS process, iCMOS, a technology platform combining the advantages of low and high voltage CMOS, bipolar and high voltage DMOS processes. The process allows the AD7366 to accept high voltage bipolar signals in addition to reducing power consumption and package size. The AD7366 can accept true bipolar analog input signals in the ±10 V range, ±5 V range and 0 to 10 V range.

The AD7366 has an on-chip 2.5 V reference that can be overdriven if an external reference is preferred. The AD7366 is available in a 24-lead TSSOP package.
