A/D converter IP block tailored for battery-powered systems

Montreal—A new 10-bit successive approximation register (SAR) A/D converter IP block has been designed for portable, battery-powered systems.

The LTR9200-T18 A/D converter IP block from LTRIM Technologies has eight multiplexed inputs and integrated sample-and-hold, enabling designers to quickly sample multiple analog sources.

The converter IP block offers a throughput rate of 1 mega-samples per second (MSPS). It also offers low-power consumption— 3.3V for analog and 1.8V for digital. In consumes 2-mA of current in active mode and 100-nA in shutdown mode.

“With one LSB max differential nonlinearity (DNL) and integral nonlinearity (INL), our new 10-bit ADC block is both fast and dependably accurate,” said Mike Shamshirian, vice president of corporate sales, in a statement. “Moreover, it draws only a couple milliamps, making it ideal for low-power, muxed input markets.”

Typical applications for the LTR9200-T18 include sensor interface/data acquisition, automotive sensors, multi-sensor wireless networks, building/home control, high-end mobile phone, biomedical devices/industrial automation, and handheld systems.

The IP block is designed in Taipei, Taiwan-based Taiwan Semiconductor Manufacturing Co. Ltd.'s 18-micron CMOS technology and can be retargeted to other foundry process technologies.

The cost of purchasing the A/D converter IP block varies since every customer needs some kind of modification, the company said.
