Its 1.2 MHz -3 dB bandwidth and 3 V/µs slew rate allow it to track fast load transients in motor drives, solenoid control, and DC-DC converter output monitoring. ## Package and mounting The 8-MSOP footprint is shared with many current-sense amplifiers and general-purpose op-amps, so board layout reuse across alternate sources is straightforward. Standard MSL 3 handling applies — bake before reflow if the moisture-barrier bag has been open past the floor-life window. It is ROHS3 compliant.","metaTitle":"LT1999IMS8-50#PBF Current Sense Amplifier, 1.2 MHz, 3 V/µs","metaDescription":"Linear Technology LT1999IMS8-50#PBF current sense amplifier: 1.2 MHz bandwidth, 3 V/µs slew rate, 4.5-5.5 V supply, -40 to 85°C, 8-MSOP.
