Monitored Alarm Systems

Complete single-chip solution provides 10-times higher accuracy than the competition

DALLAS, 24 August 2011 / PRNewswire / - Texas Instruments Incorporated (TI) (NYSE: TXN) today \ the industry's most accurate current shunt monitor. With a maximum offset voltage of 10 microvolts (uV) and a maximum gain of 0.1% of the INA226 10 times more accurate than the leading competitor. The device is a full 16-bit single-chip solution, with fully programmable measurements for current, voltage and power through a digital I2C interface. The INA226 benefits designers working with servers, telecommunications equipment, computers, power management and test equipment where precise performance measurement are critical.

Key Features and Benefits

• Single-chip digital solution with I2C interface provides current, voltage and power measurements, simplifying board design and layout constraints with no external mux or ADC required.
• Highest accuracy with a maximum offset voltage of 10 uV and maximum gain error of 0.1 percent resulting in higher accuracy at low flows and allows the use of smaller shunts, which I * R loss.
• Independent programmable conversion times and trial averaging make it easy to adjust the speed requirements of each system and reduce software and memory requirements.
