The Black Jag uses an INA193AID current-sense chip across a 0.001 ohm shunt in the high side of the bridge. The INA193's analog output is sent directly to an ADC pin in the Jag's LM3S2616 microcontroller, without any hardware (RC) filtering. And it doesn't appear that the INA193 itself is doing any low-pass filtering. The datasheet says its output bandwidth is 500KHz.

How does the the LM3S2616 firmware process this signal? Does it trigger the ADC samples to remain phase-locked with the bridge switching? Is it doing some sort of digital filtering?
