Product details

Automotive current sense with rail-to-rail output

The MAX9920ASA/V+T: The 230 kHz -3dB bandwidth and 1.5V/µs slew rate suit monitoring current in automotive DC/DC converters, solenoid drivers, and motor-drive phases. The 1 mA supply current keeps the quiescent load light on the battery line.

Housed in an 8-SOIC with exposed pad, the MAX9920ASA/V+T needs a thermal-land pattern on the PCB to pull heat from the die. The pad is electrically connected to ground — the layout should tie it to the GND plane with multiple vias under the pad. For hand-assembly or rework, the Cut Tape option avoids the reel minimum.

Frequently asked questions

What is the output type of MAX9920ASA/V+T?

Rail-to-rail output, which allows the output to swing from near the negative supply to within millivolts of the positive rail — useful for maximizing ADC input range in low-voltage systems.

Is MAX9920ASA/V+T RoHS compliant?

Yes, it is ROHS3 compliant.

What is the difference between MAX9920ASA/V+T and MAX9920ASA+T?

The /V in the suffix denotes the automotive-grade qualification (AEC-Q100). The MAX9920ASA+T is the commercial-grade variant without the AEC-Q100 certification. Electrically the two are identical, but only the /V+T version carries the automotive qualification for PPAP submissions.
