ADS1110A2IDBVR集成电路（IC）的模数转换器（ADC）规格书PDF中文资料

ADS1110A2IDBVR属于集成电路（IC）的模数转换器（ADC）。由德州仪器制造生产的ADS1110A2IDBVR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。

DESCRIPTION

The ADS1110 is a precision, continuously self−calibrating

Analog-to-Digital (A/D) converter with differential inputs and

up to 16 bits of resolution in a small SOT23-6 package. The

onboard 2.048V reference provides an input range of

±2.048V differentially. The ADS1110 uses an I2C-compatible

serial interface and operates from a single power supply

ranging from 2.7V to 5.5V.

The ADS1110 can perform conversions at rates of 15, 30, 60,

or 240 samples per second. The onboard programmable

gain amplifier (PGA), which offers gains of up to 8, allows

smaller signals to be measured with high resolution. In

single-conversion mode, the ADS1110 automatically powers

down after a conversion, greatly reducing current

consumption during idle periods.

The ADS1110 is designed for applications requiring

high-resolution measurement, where space and power

consumption are major considerations. Typical applications

include portable instrumentation, industrial process control,

and smart transmitters.
