MAX1325ECM+

MAX1325ECM+ Description

The MAX1325ECM+ is a high-performance, 14-bit successive approximation register (SAR) analog-to-digital converter (ADC) from Analog Devices Inc./Maxim Integrated. Designed for precision data acquisition, it features a 357k samples per second (SPS) sampling rate, making it suitable for high-speed signal processing. The device operates with a 5V analog supply and a flexible 2.7V to 5.25V digital supply, ensuring compatibility with mixed-voltage systems. It supports 4 single-ended inputs with a 4:1 sample-and-hold (S/H) to ADC ratio, enabling simultaneous sampling for multi-channel applications. Packaged in a 48-pin LQFP tray, it is ideal for space-constrained designs.

MAX1325ECM+ Features

• 14-bit resolution with SAR architecture for accurate, low-latency conversions.
• Parallel data interface for high-speed communication with microcontrollers or FPGAs.
• Simultaneous sampling capability across 4 channels, enhancing synchronization in multi-sensor systems.
• External or internal reference options for flexibility in precision requirements.
• Wide digital supply range (2.7V–5.25V) simplifies integration with low-power logic.
• RoHS3 compliant and REACH unaffected, meeting environmental standards.
• MSL 1 (Unlimited) moisture sensitivity, ensuring reliability in storage and assembly.
