ADS1013集成电路（IC）的模数转换器（ADC）规格书PDF中文资料

ADS1013属于集成电路（IC）的模数转换器（ADC）。由德州仪器制造生产的ADS1013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-Q1, ADS1014-Q1, and ADS1015-Q1

(ADS101x-Q1) are precision, low-power, 12-bit,

I2C-compatible, analog-to-digital converters (ADCs)

offered in VSSOP-10 and UQFN-10 packages. The

ADS101x-Q1 incorporate a low-drift voltage reference

and an oscillator. The ADS1014-Q1 and ADS1015-

Q1 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-Q1 perform conversions at data

rates up to 3300 samples per second (SPS).

The PGA offers input ranges from ±256 mV to

±6.144 V, allowing precise large- and small-signal

measurements. The ADS1015-Q1 features an input

multiplexer (MUX) that allows two differential or four

single-ended input measurements. Use the digital

comparator in the ADS1014-Q1 and ADS1015-Q1 for

under- and overvoltage detection.
