Overview
The MAX153CPP+CGP is a high-speed, microprocessor (µP)-compatible, 8-bit analog-to-digital converter (ADC) produced by Maxim Integrated, now part of Analog Devices Inc. This ADC utilizes a half-flash conversion technique to achieve a conversion time of 660ns and a sampling rate of 1 million samples per second (Msps). It is designed to operate with either single +5V or dual ±5V supplies and can accept both unipolar and bipolar input signals. The device features a power-down mode that reduces current consumption to a typical value of 1µA, making it suitable for applications requiring low power consumption.
