Product Description:

YJJ ADS1115 16-Bit High-Precision Analog-to-Digital Converter ADC Development Board Module 4 Channels

Features:

Resolution: 16-bit, no data loss
Minimum LSB voltage (PGA = 16, FS = ±0.256V): 8μV
INL integral non-linearity: ±0.5 LSB
CMRR common mode rejection ratio: DC typical 100dB, 50/60Hz mains frequency 105dB (low speed 8SPS mode)
Gain temperature drift: 5~7 ppm/℃
Built-in low drift internal reference, no need for external reference source
8 SPS / 16 SPS / 32 SPS / 64 SPS / 128 SPS (default) / 250 SPS / 475 SPS / 860 SPS (maximum)
Low speed 8SPS: optimal for mains noise suppression
High speed 860SPS: fast dynamic signal acquisition
VIII. Electrical Power Supply Parameters
Power supply voltage (analog/digital same voltage): 2.0V ~ 5.5V, compatible with 3.3V/5V microcontrollers
Operating current:
Continuous conversion mode: typical 150μA
Single conversion sleep mode: automatic power-off upon conversion completion, extremely low average power consumption of the entire device
Typical power consumption: 0.3mW
Input analog voltage range: 0V ~ VDD (single-ended)
IX. I2C Digital Interface
Standard I2C compatible, maximum rate 400kHz
4 hardware selectable addresses (ADDR pin connected to VDD/GND/SDA/SCL switch), up to 4 ADS1115 chips can be connected on a single bus
Built-in digital comparator: adjustable upper and lower thresholds, ALERT pin interrupt output, wake up MCU upon overvoltage/undervoltage trigger
X. Package Size (3 mainstream surface mount types)
X2QFN-10 (IRUGR): 2.0mm × 1.5mm × 0.4mm, ultra-small volume, wearable / micro sensor
