描述 Description

The ADS1000 is an I2C-compatible serial interface Analog-to-Digital (A/D) converter with differential inputs and 12 bits of resolution in a tiny SOT23-6 package. Conversions are performed ratiometrically, using the power supply as the reference voltage. The ADS1000 operates from a single power supply ranging from 2.7V to 5.5V.The ADS1000 performs conversions at a rate of 128 samples per second (SPS). 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 ADS1000 automatically powers down after a conversion, greatly reducing current consumption during idle periods. The ADS1000 is designed for applications where space and power consumption are major considerations. Typical applications include portable instrumentation, consumer goods, and voltage monitoring.

简介

ADS1000属于集成电路（IC）的模数转换器（ADC）。由TI制造生产的ADS1000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。
