Overview
The MAX1156BEUP+ is a 14-bit Analog-to-Digital Converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This high-performance ADC is designed for data acquisition applications and features a single-input, single-channel Accumulating-charge-Ramp (SAR) architecture. It offers a sampling rate of up to 135 kHz, making it suitable for applications requiring fast and accurate measurement of analog signals. The device operates from a single +4.75V to +5.25V analog supply and has a separate digital supply input for direct interface with +2.7V to +5.25V digital logic. The MAX1156BEUP+ is available in a compact 20-TSSOP package and is fully specified over the -40°C to +85°C extended temperature range.
