12-bit 5MSps SAR ADC IP Core by T2M
T2MIP, high-performance 12-bit successive approximation register (SAR) ADC designed for precision, speed, and ultra-low power operation. This new IP core achieves conversion rates up to 5 mega samples per second (MS/s), making it ideally suited for next-generation applications that require high-speed data acquisition with minimal power consumption.
This cutting-edge 12-bit SAR ADC IP core is specifically engineered to meet the demanding requirements of modern SoC (System on Chip) and ASIC (Application-Specific Integrated Circuit) designs. It offers a unique balance of high-resolution data conversion, excellent dynamic performance, low power consumption, and flexible configuration options. These attributes make it a perfect fit for a variety of industries including industrial automation, precision measurement systems, wireless communications, and advanced microcontroller-based applications.
The need for energy-efficient, high-precision analog interfaces continues to grow across a wide range of industries. From portable industrial devices and battery-powered sensors to high-speed communication systems and automotive control units, designers increasingly require ADCs that not only deliver performance but also minimize energy draw. T2MIP’s new SAR ADC core directly addresses this need by providing exceptional signal quality and flexible operating modes while maintaining ultra-low power consumption.
The 12-bit resolution ensures accurate signal quantization, while the 5MS/s sampling rate makes the core well-suited for fast signal processing tasks. This performance is achieved without compromising power efficiency, a feature critical for embedded systems and IoT devices where power budget is often a limiting factor.
Key Performance Metrics
One of the standout features of T2M’s new SAR ADC IP is its high dynamic performance. The converter delivers a Signal-to-Noise and Distortion Ratio (SINAD) of 70 dB and a Total Harmonic Distortion (THD) of -72 dB, which translates to an Effective Number of Bits (ENOB) of 11.3 bits. This makes it ideal for applications requiring high fidelity and accurate representation of analog signals.
Design flexibility is another cornerstone of this IP core. It supports multiple input modes—both single-ended and differential—and can handle up to four input channels. This allows designers to tailor the ADC’s input architecture to their specific system requirements, whether that involves sensing multiple voltages or improving common-mode noise rejection.
Furthermore, the ADC supports selectable resolution modes—8-bit, 10-bit, and 12-bit—allowing developers to trade off between precision and power consumption as needed. Conversion modes include both single conversion and continuous operation, providing adaptability for event-driven or real-time sampling use cases.
One of the most notable innovations in this SAR ADC IP core is its scalable power consumption architecture. In idle mode, it draws zero static (DC) power, and its dynamic power consumption is directly proportional to the clock frequency. This intelligent power scaling makes it ideal for energy-sensitive applications where processing loads vary over time.
In addition to its baseline low-power operation, the IP core also includes extended power management modes. Designers can select between low-noise and ultra-low power modes depending on the performance priorities of the system. For example, battery-powered sensors can operate in low-power mode to extend life, while instrumentation systems can switch to low-noise mode for increased accuracy.
The ADC operates at ultra-low voltages, with an analog supply range from 3.3V down to 1.8V, and a digital supply of just 1.1V. This wide supply compatibility ensures the core can be easily integrated into modern low-voltage SoC platforms without the need for costly voltage level shifters or regulators.
