ADC12DL066集成电路（IC）的模数转换器（ADC）规格书PDF中文资料

ADC12DL066属于集成电路（IC）的模数转换器（ADC）。由德州仪器制造生产的ADC12DL066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 ADC12DL066 is a dual, low power monolithic

CMOS analog-to-digital converter capable of

converting analog input signals into 12-bit digital

words at 66 Megasamples per second (Msps),

minimum. This converter uses a differential, pipeline

architecture with digital error correction and an onchip

sample-and-hold circuit to minimize die size and

power consumption while providing excellent dynamic

performance and a 450 MHz Full Power Bandwidth.

Operating on a single 3.3V power supply, the

ADC12DL066 achieves 10.7 effective bits and

consumes just 686 mW at 66 Msps, including the

reference current. The Power Down feature reduces

power consumption to 75 mW.

The differential inputs provide a full scale differential

input swing equal to 2 times VREF with the possibility

of a single-ended input. Full use of the differential

input is recommended for optimum performance. The

digital outputs from the two ADCs are available on

separate 12-bit buses with an output data format

choice of offset binary or two’s complement.

To ease interfacing to lower voltage systems, the

digital output driver power pins of the ADC12DL066

can be connected to a separate supply voltage in the

range of 2.4V to the digital supply voltage.

This device is available in the 64-lead TQFP package

and will operate over the industrial temperature range

of −40°C to +85°C. An evaluation board is available

to ease the evaluation process.
