AD6600AST集成电路（IC）的模数转换器（ADC）规格书PDF中文资料

AD6600AST属于集成电路（IC）的模数转换器（ADC）。由亚德诺半导体技术有限公司制造生产的AD6600AST模数转换器（ADC）模数转换器（ADC、A/D 或 A 转 D）对模拟信号进行采样，例如由麦克风采集的声音或传感器的输出，然后将其转换为数字信号。一般来说，数字输出是二进制补码二进制数，与输入成比例。输入类型可能是差分、伪差分或单端输入。模数转换器可按照位数、采样率、输入数、接口、转换器数和架构（例如自适应增量、双斜率、折叠、流水线、SAR、三角积分、两步式）进行选择。

PRODUCT DESCRIPTION

The AD6600 mixed-signal receiver chip directly samples signals at analog input frequencies up to 250 MHz. The device includes two input channels, each with 1 GHz input amplifiers and 30 dB of automatic gain-ranging circuitry. Both channels are sampled with a 450 MHz track-and-hold followed by an 11-bit, 20 MSPS analog-to-digital converter. Digital RSSI outputs, an A/B channel indicator, a 2× Clock output, references, and con trol circuitry are all on-chip. Digital output signals are two’s complement, CMOS-compatible and interface directly to 3.3 V or 5 V digital processing chips.
