Overview
The MAX154BEAG+ is a high-speed, multi-channel analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This component is part of the MAX154 series, which includes devices with four or eight analog input channels. The MAX154BEAG+ specifically features four analog input channels, making it a versatile option for various data acquisition applications.
The device operates on a single +5V supply and includes a built-in track/hold circuit, eliminating the need for external track/hold components. It also features a 2.5V on-chip reference, which forms a complete high-speed data acquisition system. The ADC uses a 'half-flash' conversion technique, combining two 4-bit flash ADC sections to achieve an 8-bit result.
