Touchstone intros low-power current-sense amplifiers

MILPITAS, USA: Touchstone Semiconductor, a provider of high-performance analog integrated circuit solutions, has announced the TS1100 family of 1µA current-sense amplifiers that cut offset to 30µV, over 3X tighter than the closest competitor. 

The tight offset allows users to not have to increase power consumption in order to achieve improved accuracy. This is something that cannot be done with any other low power current sense amplifier. The TS1100 is available in four gain options from 25V/V to 200V/V, so customers can choose the ideal gain option for their unique application, said a press release.

The TS1100 family’s combination of small form factor (SOT23-5), low supply current operation and variety of fixed gain options make it an ideal choice for low current, high-side current-sensing amplification. 

The TS1100 is particularly suitable for use in all battery-powered, remote or hand-held portable instruments, including power management applications, motor control, power management and fixed-platform telecom boxes, the release added.
