The -3 dB bandwidth is 400 kHz with a slew rate of 2 V/µs. That bandwidth covers the switching ripple in a typical 100–200 kHz DC-DC converter and lets the amplifier track the current waveform through the inductor. If you're monitoring a motor phase current with a PWM carrier at 20 kHz, the 400 kHz bandwidth gives you enough headroom to reconstruct the current envelope without phase lag that would throw off the control loop. ## Supply range and quiescent draw The 1.8 mA supply current is the quiescent draw, a fixed load in always-on systems. That means no last-time-buy scramble for a new BOM line. The base product number is INA240, and the A2 variant is the mid-gain option (20 V/V). If you need a different gain, the INA240A1 (50 V/V) and INA240A3 (100 V/V) are pin-compatible siblings in the same 8-TSSOP footprint.","metaTitle":"INA240A2PW Current-Sense Amplifier, 400 kHz, 5 µV Offset","metaDescription":"TI INA240A2PW current-sense amplifier in 8-TSSOP. 400 kHz bandwidth, 5 µV input offset, 2.7-5.5 V supply.
