Description

Six Gold Edition ADS1115 modules: a real 16-bit analog-to-digital converter on two I2C wires, for when your microcontroller's own analog input is not precise enough.

Highlights

• Four inputs per module. Read 4 single-ended channels or 2 differential pairs.
• Programmable gain. Six full-scale ranges from ±6.144 V down to ±0.256 V, as fine as 7.8 µV per count.
• Two per I2C bus. 0x48 as shipped, 0x49 with the ADDR pad bridged, so two modules share one bus for eight channels.
• 3.3 V or 5 V. Runs from 2.0 V to 5.5 V, so it talks to 3.3 V and 5 V boards without a level shifter.
• Ready to plug in. Headers fitted, ENIG gold finish, lead-free.

In the box
