The 13Bit 5MS/s SAR ADC is the newly added IP to our portfolio, with a 8:1 input MUX. It features a single-ended input configuration with a superior GND noise immunity. With its versatile capabilities, this IP is ideally suited for a wide range of applications, including IoT networks, motor control systems, data acquisition platforms, automotive solutions, and housekeeping functions.

Key Features and Specifications

The converter combines advanced technology with practical features to address the rigorous demands of multi-channel data acquisition and high-resolution signal processing. The design tracks ground noise in single-ended mode, ensuring robust signal integrity.

Performance Highlights

    • 13-bit Resolution: Delivers high precision with an effective sampling rate of 2.2MS/s at a clock frequency of 60MHz.

    • Wide Input Range: Supports a 1.5Vpp full-scale input, ideal for applications requiring a wide dynamic range and high common-mode rejection.

    • Calibration-Free Design: Ensures >11-bit static linearity and overlapping decision levels without additional calibration steps.

    • High Input Bandwidth: Guarantees wide-band signal tracking with a Track-and-Hold input bandwidth exceeding 2MHz.

Key Functionality

    • 8:1 Input Multiplexer (MUX): Offers multi-channel discretization, with all MUX inputs configurable to high Z-mode.

    • On-Chip Reference: Includes a buffered internal reference voltage (1.5V), also available externally for additional flexibility.

    • Digital Overrange Calibration: Ensures accurate performance over varying conditions.

    • CMOS-Compatible Input: Operates on a 1.8V single supply, making it power-efficient and easy to integrate.

    • 2's Complement Data Format: Simplifies digital signal processing.

    • Wide Operating Temperature Range: Performs reliably in extreme environments, from -40°C to 125°C.

    • Compact Core Area: With a silicon footprint of 280 x 450 µm², it is well-suited for I/Q receiver applications requiring efficient use of space.

    • Noise Resilience: Tracks ground noise in single-ended mode, ensuring robust signal integrity.
