The 1 MHz -3 dB bandwidth supports fast overcurrent detection and switching-load monitoring in motor drives, power supplies, and solenoid control. ## 10 µV input offset — accuracy at low shunt drops The 10 µV input offset voltage is the key spec for precision. At a 10 mV full-scale shunt drop, the offset contributes only 0.1% error. This matters when the shunt is sized for low power dissipation — a 1 mΩ shunt carrying 10 A drops only 10 mV, and the 10 µV offset keeps the reading accurate without a larger, more dissipative resistor. The 20 µA input bias current is drawn from the shunt, so keep that in mind when the shunt resistance is high (above 100 Ω). The 2.5 V/µs slew rate combined with the 1 MHz bandwidth means the output can track a step change in load current within a few microseconds. For a motor-drive PWM cycle at 20 kHz, the amplifier settles before the next switching edge. The 1.5 mA supply current is a fixed overhead — it does not scale with load, so it is a constant drain in battery-powered designs.","metaTitle":"TI INA293A3IDBVT Current Sense Amplifier, 1 MHz Bandwidth","metaDescription":"Texas Instruments INA293A3IDBVT current sense amplifier in SOT-23-5. 2.7 V to 20 V supply, 10 µV offset, -40°C to 125°C.
