The ADS1113, ADS1114, and ADS石斛的禁忌 11春节礼品大全 15 are precision analog-to-digital

converters (ADCs) with 16 bits of resolution offered in an ultra-small, leadless

QFN-10 package or an MSOP-10 package. The ADS1113/4/5 are designed

with precision, po惭愧的反义词 wer, and ea of implementation in mind. The ADS1113/4/5

feature an onboard reference and oscillator. Data are transferred via an

IC-compatible rial interface; four IC slave address can be lected. The

ADS1113/4/5 operate from a single power supply ranging from 2.0V to 5.5V.

The ADS1113/4整改落实情况报告 /5 can perform conversions at rates up to 860 samples per

cond (SPS). An onboard PGA is available on the ADS1114 and ADS1115

that offers input ranges from the supply to as low as 256mV, allowing both

large and small signals to be measured with high resolution. The ADS1115

also features an input multiplexer (MUX) that provides two differential or four

single-ended inputs.

The ADS1113/4/5 operate either in continuous conversion mode or a

single-shot mode that automatically powers down after a conversion and

greatly reduces current consumption during idle periods. The ADS1113/4/5 are

specified from –40℃to +125℃.
