Working voltage (): 2.3V-5.5V (note: When using Qwiic cable for power supply, the working voltage Only 3.3V);Working temperature: -40 ° C to 125 ° C;Working mode: single trigger, continuous conversion, and shutdown; Analog input: Four way single ended Can be configured as one or two differential inputs reference voltage input VDDA (AVDD) can also be configured through and branch pads resolving power: Maximum 24 digits, 20 digits valid LSB size (gain x1): 244.14nV LSB size (gain x4): 61.04nV S ampling rate: 20 Hz to 1 kHz Combination current consumption (typical): 8 μ A-410 μ A 50Hz and 60Hz noise suppression Configurable input multiplexer Sixteen configurable 12C addresses: 0x40 - 0x4F Default value: 0x40 2 Qwiic connection ports Power indicator light (configurable) The ADS1219 24 bit ADC can provide four 12C controlled ADC input channels. These channels can be used as single ended inputs or paired for differential inputs, with sampling rates up to 1kHz. What makes this ADC more powerful is that it has a programmable x1 or x4 gain amplifier that allows you to "amplify" small changes in analog voltage. Color: Black Material: plastic Package Contents: 1*24-bit AD Sampling Module Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
