3 Description

The ADC3541, ADC3542 and ADC3543 (ADC354x)

family of devices are low-noise, ultra-low power,

14-bit, 10 to 65-MSPS, high-speed analog-todigital

converters (ADCs). Designed for low power

consumption, these devices deliver a noise spectral

density of –155 dBFS/Hz. The ADC354x offers great

dc precision together with IF sampling support,

which make these devices 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 79 mW at 65 MSPS, and

the power consumption scales very well with lower

sampling rates.

The ADC354x uses an SDR, DDR or a serial

CMOS interface to output the data offering the lowest

power digital interface, together with the 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°C to

+105⁰C.

ADC3542IRSBT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ADC3542IRSBT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。
