MCP3421 18-Bit ADC Module Built-in Programmable Gain Amplifier Plug and Description

18-bit High-Precision ADC: Powered by the MCP3421-a single-channel, low-noise Delta- ADC-it offers 18-bit resolution, enabling precise capture of minute voltage fluctuations.
Differential Input & Programmable Gain: Features a differential input architecture supporting both positive and negative signal measurements; includes a built-in Programmable Gain Amplifier (PGA) with four gain settings (x1, x2, x4, x8) to accommodate signal sources of varying amplitudes.
Flexible Data Rates: Allows switching between four combinations of resolution and sampling rate-18-bit (3.75 SPS), 16-bit (15 SPS), 14-bit (60 SPS), and 12-bit (240 SPS)-striking a balance between precision and speed.
Plug-and- Connectivity: Utilizes STEMMA QT / Qwiic standard interfaces for quick, solder-free connections and supports daisy-chaining to simplify system wiring.
High Precision & Low Power: Combines 18-bit resolution and an integrated high-precision voltage reference with ultra-low power consumption, making it ideal for precision measurement and portable applications.
