TI ADS1115 16位精密模数转换方案

TI公司的ADS1113, ADS1114和ADS1115是超小型16位精密模数转换器(ADC),具有板载基准电压和振荡器,通过I2C兼容接口传输数据,工作电压从2.0V到5.5V,取样频率高达860SPS,.连续模式的功耗仅为150uA, 工作温度从–40℃ 到+140℃,可用在手提仪表,消费类产品,电池监视,温度测量以及工厂自动化和过程控制.本文介绍了ADS1113, ADS1114和ADS1115的主要特性,方框图, 基本硬件配置图, 典型连接图, 多个ADS1113/4/5连接图以及评估板ADS1015EVM/ADS1115EVM电路图和材料清单.

The ADS1113, ADS1114, and ADS1115 are precision analog-to-digital converters (ADCs) with 16 bits of resolution offered in an ultra-small, leadless QFN-10 package or an MSOP-10 package. The ADS1113/4/5 are designed with precision, power, and ease of implementation in mind. The ADS1113/4/5 feature an onboard reference and oscillator. Data are transferred via an I2C-compatible serial interface; four I2C slave addresses can be selected. The ADS1113/4/5 operate from a single power supply ranging from 2.0V to 5.5V.
