ADS1113集成电路（IC）的模数转换器（ADC）规格书PDF中文资料

ADS1113属于集成电路（IC）的模数转换器（ADC）。由德州仪器制造生产的ADS1113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。

3 Description

The ADS1113-Q1, ADS1114-Q1, and ADS1115-Q1

devices (ADS111x-Q1) are precision, low-power,

16-bit, I2C-compatible, analog-to-digital converters

(ADCs) offered in VSSOP-10 and UQFN-10

packages. The ADS111x-Q1 devices incorporate a

low-drift voltage reference and an oscillator. The

ADS1114-Q1 and ADS1115-Q1 also incorporate a

programmable gain amplifier (PGA) and a digital

comparator. These features, along with a wide

operating supply range, make the ADS111x-Q1 well

suited for power- and space-constrained, sensor

measurement applications.

The ADS111x-Q1 perform conversions at data rates

up to 860 samples per second (SPS). The PGA offers

input ranges from ±256 mV to ±6.144 V, allowing

precise large- and small-signal measurements. The

ADS1115-Q1 features an input multiplexer (MUX)

that allows two differential or four single-ended

input measurements. Use the digital comparator in

the ADS1114-Q1 and ADS1115-Q1 for under- and

overvoltage detection.
