35 kHz bandwidth — enough for DC rail monitoring and load-step detection
The INA186A3IDCKR: With a gain-bandwidth product of 35 kHz and a 0.3 V/µs slew rate, this amplifier is sized for monitoring DC current on power rails, battery charge/discharge profiles, and load-step events where the bandwidth of interest stays below a few kilohertz. It is not intended for high-frequency switching-current waveforms — that role belongs to parts like the INA254A1IPWAR with its 350 kHz bandwidth. For a motor-drive bus monitor or a telecom line-card current sensor, the 35 kHz corner is adequate and keeps noise from aliasing into the measurement.
SC-70-6 package — board-area conscious
Housed in a 6-pin SC-70 (SOT-363) package with surface-mount termination, this amplifier fits into space-constrained layouts such as battery-pack monitor PCBs, handheld instruments, and sensor modules. The SC-70-6 footprint is common enough that layout libraries and solder-paste stencils are widely available. No special thermal management is needed at 48 µA supply current.
The 125°C maximum junction temperature allows placement near hot components like MOSFETs or inductors without derating the supply current.
