The SGM830 is a high-accuracy, fixed-gain, voltage- output, current-sense amplifier featuring a wide common-mode voltage range from -4V to 80V. This negative common-mode voltage enables operation below ground level, useful in scenarios like the flyback period of a solenoid.
The SGM830 provides low offset voltage, small gain error and excellent DC CMRR. Its small-signal bandwidth can reach up to 1MHz, with an AC CMRR of 70dB at 50kHz. These characteristics make accurate current measurement without large transients and related recovery disturbances on the output voltage. It is suitable for both DC current measurement and high speed applications such as fast over-current protection.
The device is powered from a single 2.7V to 18V supply, and draws 1.2mA (TYP) of supply current. There are five fixed gain options: 20V/V, 50V/V, 100V/V, 200V/V, and 500V/V, providing more flexibility to fit the gain requirements in various applications.
The SGM830 is available in a Green SOT-23-5 package.
