The SQ52132 is a 100V/V fixed-gain current sense amplifier featuring high accuracy, high bandwidth, and a wide common-mode voltage range from –4V to 80V, independent of the supply voltage. This wide common-mode voltage facilitates use in high-side current-sense applications, and its capability to handle negative common-mode voltages enables operation in low-side current-sense applications, including those below ground.
The SQ52132 features low offset voltage, minimal gain error, and high DC Common Mode Rejection Ratio (CMRR), enabling precise current measurements. With a bandwidth of 1MHz and an AC CMRR of 80dB at 50kHz, the device is suitable for high-speed applications.
The supply voltage range of the SQ52132 is 2.7V to 5.5V, and the device draws 1.3mA quiescent current. It is available in a SOT23-5 package and is specified for the extended industrial temperature range of -40°C to 125°C.
