Hua Hong Semiconductor introduced 12-bit SAR ADC IP power ultra-low-power MCU platform

(BUSINESS WIRE) - Hua Hong Semiconductor Co., Ltd., the world's leading 200-mm pure foundry, today announced the release of its 0.11-micron Ultra-Low-Leakage (ULL) Embedded Flash (eFlash) State-of-the-art, ultra-low power, 12-bit SAR analog-to-digital converter (ADC) with its own design, the ADC IP is silicon proven and has up to 2MSPS Sampling rate and combines the excellent features of multi-channel, high precision, low power consumption and is ideally suited for high-performance microcontroller (MCU) products as well as various multivariate including IoT Application.

12-Bit SAR ADC Features

Relying on its outstanding R & D team and rich experience in IP design, Hua Hong Semiconductor is targeting the growing MCU market. In addition to embedded memory IP, Hua Hong Semiconductor has introduced RTC, BGR, LDO, PORI, PORE, RC OSC, LCD driver, And other series of analog IP. Among them, the ADC IP is a 12-bit resolution SAR ADC, monotonous transfer characteristics, no missing codes; IP area of ​​only 0.2mm2, reducing the cost of the chip; available in the supply voltage of 1.8V to 5.5V, Temperature -40 ℃ to +125 ℃ in a wide range of stable work.

12-Bit SAR ADC Dynamic Performance

The 12-Bit SAR ADC IP features ultralow power consumption: 3.3V supply voltage and 3.5mW power consumption at 2MSPS sample rate; 1.8mW power consumption at 2MSPS at 2.0V supply voltage.

The 12-Bit SAR ADC IP has excellent dynamic performance with a signal-to-noise distortion ratio of 70dB over SNDR at a 3.3V sample rate at 2MSPS and a sample rate of up to 1.5MSPS at supply voltages as low as 1.8V. The signal noise is less distorted than the SNDR Is 69dB.

The 12-Bit SAR ADC IP has ten external input signal channels (eight of which are flexibly configurable to operate in differential or single-ended mode and the other two to measure external reference voltages) and an internal input signal path Measurement of supply voltage), built-in digital calibration circuit, which can correct the offset of the internal comparator and the linearity error of the internal digital-to-analog converter, and the positive and negative reference voltages and the length of the sampling period can be selected and configured.

HONG KONG Semiconductor Executive Vice President Dr. Kong Weirran said: '12 -Bit SAR ADC IP launch reflects the company's independent research and development capabilities as an important component of Hua Hong Semiconductor MCU series solutions, the ADC IP ultra-low 0.11-micron The successful ULL eFlash technology platform enables customers to effectively reduce chip power consumption and cost, simplify and speed up system design, and enhance their competitiveness in the Internet of Things, industrial and automotive markets.
