MAX1274BETC+T

Introduction

The MAX1274BETC+T is a mixed-mode analog-to-digital converter (ADC) designed to provide a high resolution, low power and small size solution for applications ranging from consumer to industrial. The MAX1274BETC+T allows for direct connection of a wide variety of sensors, eliminating the need for external components. It is suitable for waveform sampling and data conversion from DC signals to high-speed waveforms.

Working Principle

The MAX1274BETC+T consists of a 12-bit successive approximation (SAR) type A/D converter with a built-in flash analog-to-digital converter. The SAR type A/D converter features a 0.5μs conversion speed and a 7μs settling time. The flash analog-to-digital converter has an input range of 4V to 16V and a maximum conversion speed of 111MSPS (million samples per second). The device also contains an on-chip reference voltage and voltage reference with 3.2V output.The MAX1274BETC+T utilizes two-step A/D conversion technology to process the analog signals. First, a signal is pre-scaled by the flash analog-to-digital converter to meet the internal requirements of the successive approximation converter. The pre-scaled signal is then applied to the successive approximation converter which converts the analog signal into a Digital signal. The output of the A/D conversion is a 12-bit serial data stream, which is then outputted with an output resolution of 12-bits or 16-bits. The total-power consumption of the MAX1274BETC+T is very low, due to its low-noise and low-power architectures, making it suitable for battery-powered applications. Also, the fast conversion of the flash A/D converter allows for fast processing of waveform data.
