Product Description
| [Description] The ADS1015 four channel splitter board is perfect for adding high-resolution analog-to-digital conversion to any microprocessor-based project. These circuit boards can run power and logic signals between 2V and 5V, making them compatible with all common 3.3V and 5V processors. Four of the circuit boards can be controlled from the same 2-wire I2C bus, providing up to 16 single ended or 8 differential channels. Programmable gain amplifiers provide up to x16 gain for small signals. |
| [Parameters] Power/Logic Level: 2.0V to 5.5V Low current consumption: Continuous mode: Only 150 μ A Single shot mode: Automatic shutdown Resolution: 12 bits Programmable sampling rate: 128 to 3300 samples per second Internal low drift voltage reference Internal oscillator Internal: PGX16 I2C interface: 4-pin optional address Four single ended or two differential inputs Programmable comparator |
| [Pin Description] VDD: Positive power supply (3.3V/5V) GND: Ground, negative power supply SCL: IIC clock line SDA: IIC Data Cable ADDR: Determine IIC slave address ALRT: Digital comparator output or conversion ready A0: Differential channel 1, positive input or single ended channel 1 input A1: Differential channel 1, negative input or single ended channel 2 input A2: Differential channel 2, positive input or single ended channel 3 input A3: Differential channel 2, negative input or single ended channel 4 input |
| [Instructions for Use] The IIC bus of the module has a pull-up resistor, so users do not need to pull it up. The module defaults to a 7-bit IIC address of 0x48 (1001000), and the chip uses a clever addressing method that allows the use of one address pin (ADDR) to achieve four different addresses. When the ADDR is grounded, the IIC address is 0x48 (1001000). When the ADDR is connected to VDD, the IIC address is 0x49 (1001001). When the ADDR is connected to SDA, the IIC address is 0x4A (1001010). When the ADDR is connected to SCL, the IIC address is 0x4B (1001011) |
