Overview
The MAX11331ATJ+T is a high-speed, low-power analog-to-digital converter (ADC) designed by Analog Devices Inc./Maxim Integrated. This 12-/10-bit ADC features an external reference and a 500kHz full-linear bandwidth, making it suitable for applications requiring high-speed data conversion with low power consumption. The device uses serial-output successive approximation register (SAR) architecture and supports both internal and external clock modes, as well as a scan mode. The internal clock mode includes internal averaging to enhance the signal-to-noise ratio (SNR), while the external clock mode utilizes SampleSet™ technology for user-programmable analog input channel sequencing, reducing the communication overhead for controlling units such as microcontrollers or DSPs.
