Overview
The MAX120EWG+ is a high-performance, 12-bit analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This component is part of the MAX120/MAX122 series, which are complete, BiCMOS, sampling ADCs. These converters combine an on-chip track/hold (T/H) and a low-drift voltage reference, offering fast conversion speeds and low power consumption. The MAX120EWG+ is particularly noted for its high throughput rates and compatibility with various microprocessor interfaces, making it suitable for a wide range of applications.
