For microcontrollers without an analog-to-digital converter or when you want a higher-precision ADC, the ADS1115 provides 16-bit precision at 860 samples/second over I2C. The chip can be configured as 4 single-ended input channels, or two differential channels. As a nice bonus, it even includes a programmable gain amplifier, up to x16, to help boost up smaller single/differential signals to the full range. We like this ADC because it can run from 2V to 5V power/logic, can measure a large range of signals and its super easy to use. It is a great general purpose 16 bit converter./對於沒有模數轉換器的微控制器或當您需要更高精度的 ADC 時,ADS1115 通過 I2C 以 860 樣本/秒的速度提供 16 位精度。該芯片可配置為 4 個單端輸入通道,或兩個差分通道。作為一個不錯的獎勵,它甚至包括一個高達 x16 的可編程增益放大器,以幫助將較小的單/差分信號提升到全範圍。我們喜歡這個 ADC,因為它可以從 2V 到 5V 電源/邏輯運行,可以測量大範圍的信號,並且超級易於使用。它是一款出色的通用 16 位轉換器。
The chip's fairly small so it comes on a breakout board with ferrites to keep the AVDD and AGND quiet. Interfacing is done via I2C. The address can be changed to one of four options (see the datasheet table 5) so you can have up to 4 ADS1115's connected on a single 2-wire I2C bus for 16 single ended inputs./該芯片相當小,因此它帶有一個帶有鐵氧體的分線板,以保持 AVDD 和 AGND 安靜。接口是通過 I2C 完成的。地址可以更改為四個選項之一(請參見數據表表 5),因此您可以在單個 2 線 I2C 總線上連接多達 4 個 ADS1115,用於 16 個單端輸入。
Comes with a bit of 0.1" standard header in case you want to use it with a breadboard or perfboard. Four mounting holes for easy attachment. /附帶一點 0.1" 標準接頭,以防您想將其與麵包板或穿孔板一起使用。四個安裝孔便於安裝。
To get you going fast, we spun up a custom-made PCB in the STEMMA QT form factor, making it easy to interface with. The STEMMA QT connectors on either side are compatible with the SparkFun Qwiic I2C connectors. This allows you to make solderless connections between your development board and the ADS1115 or to chain it with a wide range of other sensors and accessories using a compatible cable./為了讓您快速上手,我們推出了STEMMA QT 外形的定制 PCB ,使其易於連接。 兩側的 STEMMA QT 連接器與 SparkFun Qwiic I2C 連接器兼容。這使您可以在開發板和 ADS1115 之間進行無焊連接,或使用兼容電纜將其與各種其他傳感器和附件鏈接。
QT Cable is not included, but we have a variety in the shop./QT電纜不包括在內,但我們在商店裡有各種各樣的電纜
We have example code for both the Raspberry Pi, Arduino, and CircuitPython. Simply connect GND to ground, VDD to your logic power supply, and SCL/SDA to your microcontroller's I2C port and run the example code to start reading data./ 我們有 Raspberry Pi、Arduino 和 CircuitPython 的示例代碼。只需將 GND 接地,將 VDD 連接到邏輯電源,將 SCL/SDA 連接到微控制器的 I2C 端口,然後運行示例代碼即可開始讀取數據。
