ADS1015IDGSR集成电路（IC）的模数转换器（ADC）规格书PDF中文资料

ADS1015IDGSR属于集成电路（IC）的模数转换器（ADC）。由德州仪器制造生产的ADS1015IDGSR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 ADS1013, ADS1014, and ADS1015 (ADS101x)

are precision, low-power, 12-bit, I2C-compatible,

analog-to-digital converters (ADCs) offered in a

leadless X2QFN-10, a SOT-10, and a VSSOP-10

package. The ADS101x incorporates a low-drift

voltage reference and an oscillator. The ADS1014

and ADS1015 also incorporate a programmable gain

amplifier (PGA) and a digital comparator. These

features, along with a wide operating supply range,

are useful for power- and space-constrained, sensor

measurement applications.

The ADS101x perform conversions at data rates

up to 3300 samples per second (SPS). The PGA

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

precise large- and small-signal measurements. The

ADS1015 features an input multiplexer (MUX) that

allows two differential or four single-ended input

measurements. Use the digital comparator in the

ADS1014 and ADS1015 for under- and overvoltage

detection.
