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

+105?C.

ADC3541屬于集成電路（IC） > 模數(shù)轉(zhuǎn)換器（ADC）。美國(guó)德州儀器公司制造生產(chǎn)的ADC3541模數(shù)轉(zhuǎn)換器（ADC）模數(shù)轉(zhuǎn)換器（ADC、A/D 或 A 轉(zhuǎn) D）對(duì)模擬信號(hào)進(jìn)行采樣，例如由麥克風(fēng)采集的聲音或傳感器的輸出，然后將其轉(zhuǎn)換為數(shù)字信號(hào)。一般來(lái)說(shuō)，數(shù)字輸出是二進(jìn)制補(bǔ)碼二進(jìn)制數(shù)，與輸入成比例。輸入類型可能是差分、偽差分或單端輸入。模數(shù)轉(zhuǎn)換器可按照位數(shù)、采樣率、輸入數(shù)、接口、轉(zhuǎn)換器數(shù)和架構(gòu)（例如自適應(yīng)增量、雙斜率、折疊、流水線、SAR、三角積分、兩步式）進(jìn)行選擇。
