ADC12DS080集成电路（IC）的模数转换器（ADC）规格书PDF中文资料

ADC12DS080属于集成电路（IC）的模数转换器（ADC）。由德州仪器制造生产的ADC12DS080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。

DESCRIPTION

The ADC12DS080 is a high-performance CMOS

analog-to-digital converter capable of converting two

analog input signals into 12-bit digital words at rates

up to 80 Mega Samples Per Second (MSPS). The

digital outputs are serialized and provided on

differential LVDS signal pairs. This converter uses a differential, pipelined architecture with digital error

correction and an on-chip sample-and-hold circuit to

minimize power consumption and the external

component count, while providing excellent dynamic

performance. The ADC12DS080 may be operated

from a single +3.0V or 3.3V power supply. A power-

down feature reduces the power consumption to very

low levels while still allowing fast wake-up time to full

operation. The differential inputs accept a 2V full

scale differential input swing. A stable 1.2V internal

voltage reference is provided, or the ADC12DS080

can be operated with an external 1.2V reference. The

selectable duty cycle stabilizer maintains

performance over a wide range of clock duty cycles.

A serial interface allows access to the internal

registers for full control of the ADC12DS080's

functionality. The ADC12DS080 is available in a 60-

lead WQFN package and operates over the industrial

temperature range of −40°C to +85°C
