3 Description

The ADC364x family of devices are low-noise,

ultra-low power, 14-bit, 10-MSPS to 65-MSPS

dual-channel, high-speed analog-to-digital converters

(ADCs). Designed for low power consumption, these

devices deliver a noise spectral density of –155

dBFS/Hz, combined with excellent linearity and

dynamic range. The ADC364x offers very good dc

precision, together with IF sampling support, which

make the device an excellent choice for a wide range

of applications. High-speed control loops benefit from

the short latency of only one clock cycle. The ADC

consumes only 72 mW/ch at 65 MSPS, and power

consumption scales well with lower sampling rates.

The ADC364x use a DDR or serial CMOS interface to

output the data offering lowest power digital interface,

together with flexibility to minimize the number of

digital interconnects. These devices are a pin-to-pin

compatible family with different speed grades. These

devices support the extended industrial temperature

range of –40 to +105⁰C.

ADC3642属于集成电路（IC） > 模数转换器（ADC）。美国德州仪器公司制造生产的ADC3642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。
