The host reads converted data through I2C at address 0x48, while the onboard programmable gain amplifier supports gains of 1, 2, 4, or 8 for signals with different amplitudes.\u003c\/p\u003e\u003cp\u003eThe unit is useful for sensor outputs, process-control signals, portable instruments, factory automation prototypes, and measurement systems that need more resolution than a typical microcontroller ADC.\u003c\/p\u003e\u003ch2\u003eMeasure Low-Level Analog Signals with Programmable Gain\u003c\/h2\u003e\u003cp\u003eThe PGA can increase sensitivity for smaller input signals, but gain selection also reduces the allowable full-scale input range. Choose gain only after checking the expected signal amplitude and source impedance, and prevent the analog input from exceeding the supported electrical limits.\u003c\/p\u003e\u003ch3\u003eI2C Integration at Address 0x48\u003c\/h3\u003e\u003cp\u003eUsing I2C lets the host collect high-resolution data without implementing the converter timing directly. Check address conflicts, bus pull-ups, cable length, grounding, and noise coupling before combining the ADC with other peripherals.\u003c\/p\u003e\u003ch3\u003eResolution Is Not the Same as Absolute Accuracy\u003c\/h3\u003e\u003cp\u003eA 16-bit converter provides fine digital resolution, but final measurement accuracy also depends on reference stability, analog front-end design, source impedance, gain setting, calibration, temperature drift, grounding, and electrical noise. Validate the assembled measurement chain against a suitable reference when accuracy matters.\u003c\/p\u003e\u003ch2\u003eProtect the Analog Input\u003c\/h2\u003e\u003cp\u003eThe existing product specification lists a DC input range up to 12V for the complete unit. Confirm wiring and signal limits before connection, and add appropriate protection when the source can generate transients or fault voltages.\u003c\/p\u003e","brand":"LogicBoundless","offers":[{"title":"Default Title","offer_id":49240512594135,"sku":"LB-M5-U013-V11","price":8.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/8952\/2135\/files\/1_0559c421-5971-42c1-9d9b-a785a45b717c.webp?v=1783243353","url":"https:\/\/logicboundless.com\/products\/m5stack-ads1110-16bit-adc-i2c-unit-v11","provider":"LogicBoundless","version":"1.0","type":"link"}
