26 March 2012 1µA current sense amplifier reduces power by 30 times 1µA current sense amplifier reduces power by 30 times Touchstone Semiconductor has announced the first bidirectional, symmetrical, high side current sense amplifier. According to the ic specialist, the TS1101 consumes only 1µA, - 30 times less than the closest competing product. The device's symmetrical architecture is designed to eliminate the 'dead band' when switching from measuring battery discharge to measuring battery charge. Touchstone says this breakthrough significantly simplifies customer designs while reducing power, saving board space and improving system accuracy. Touchstone adds that the TS1101 features an input offset voltage guaranteed to be 100µV, a four times improvement over the closest competing part. The device is available in four gain options from 25 to 200V/V. "The TS1101 defines a new state of the art in current sense amplifiers," said Adolfo Garcia, vice president of Marketing at Touchstone. "It sets a new standard in ease of use, simplicity and performance." The amplifer is designed for low current, high side current sensing amplification in applications such as battery powered and portable devices, including mobile phones, notebook computers and power management systems. It is fully specified over the extended temperature range of -40 to 105°C.
