ADC12DC105CISQE/NOPB集成电路（IC）的模数转换器（ADC）规格书PDF中文资料

ADC12DC105CISQE/NOPB属于集成电路（IC）的模数转换器（ADC）。由德州仪器制造生产的ADC12DC105CISQE/NOPB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 ADC12DC105 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 105 Mega Samples Per Second (MSPS). These

converters use a differential, pipelined architecture

with digital error correction and an on-chip sampleand-

hold circuit to minimize power consumption and

the external component count, while providing

excellent dynamic performance. A unique sample-

and-hold stage yields a full-power bandwidth of 1

GHz. The ADC12DC080/105 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 provide a 2V full

scale differential input swing. A stable 1.2V internal

voltage reference is provided, or the ADC12DC105

can be operated with an external 1.2V reference.

Output data format (offset binary versus 2's

complement) and duty cycle stabilizer are pin•

selectable. The duty cycle stabilizer maintains

performance over a wide range of clock duty cycles.

The ADC12DC105 is available in a 60-lead WQFN

package and operates over the industrial temperature

range of −40°C to +85°C.
