Maxim Integrated MAX1383ATP

Description
The MAX1377/MAX1379/MAX1383 are dual, 12-bit, 1.25Msps simultaneous-sampling ADCs with a serial interface and internal voltage reference. They offer low power dissipation, excellent dynamic performance, and a fast sampling rate, making them suitable for industrial process control, motor control, and RF applications.
