Overview
The MAX11195ATE+ is a part of the MAX11192/MAX11195/MAX11198 family of dual-channel Successive Approximation Register (SAR) Analog-to-Digital Converters (ADCs) produced by Analog Devices Inc./Maxim Integrated. These ADCs are designed for high-performance applications requiring simultaneous sampling at a throughput rate of 2 million samples per second (Msps). The MAX11195ATE+ specifically offers 14-bit resolution and features differential inputs, making it suitable for a variety of precision measurement tasks.
The device is packaged in a compact 16-pin, 3mm x 2mm ultra TDFN package, which is RoHS-compliant. It operates over a supply voltage range of 3.0V to 5.25V and is designed to work within an extended industrial temperature range of -40°C to +125°C. An integrated reference further enhances its performance by reducing board area and component count.
