产品说明

The ADS1115-Q1 device is a precision analog-to-digital converter (ADCs) with 16 bits of resolution offered in an ultra-small, leadless QFN-10 package or an VSSOP-10 package. The ADS1115-Q1 is designed with precision, power, and ease of implementation in mind. The ADS1115-Q1 feature an onboard reference and oscillator. Data are transferred via an I2C-compatible serial interface; four I2C slave addresses can be selected. The ADS1115-Q1 operates from a single power supply ranging from 2 V to 5.5 V.

The ADS1115-Q1 can perform conversions at rates up to 860 samples per second (SPS). An onboard PGA is available on the ADS1115 that offers input ranges from the supply to as low as ±256 mV, allowing both large and small signals to be measured with high resolution. The ADS1115 also features an input multiplexer (MUX) that provides two differential or four single-ended inputs.

The ADS1115-Q1 operate either in continuous conversion mode or a single-shot mode that automatically powers down after a conversion and greatly reduces current consumption during idle periods. The ADS1115-Q1 is specified from –40°C to 125°C.
