Shutdown Control

The shutdown may be enabled by either logic high or logic low that depending on shutdown mode selection. Both the

SD pin and the SD Mode pin are TTL compatible input. The SD Mode is logic low, the device entries shutdown when

SD is logic low. The SD Mode is logic high, the device entries shutdown when SD is logic high.

High Pass Filter

Thermal pad considerations

The thermal pad must be connected to ground. The package with thermal pad of the MS6901 requires special attention

on thermal design. The thermal pad on the bottom of the MS6901 should be soldered down to a copper pad on the

circuit board. Heat can be conducted away from the thermal pad through the copper plane to ambient. If the copper

plane is not on the top surface of the circuit board, 9 vias of 13 mil or smaller in diameter should be used to thermally

couple the thermal pad to the bottom plane. For good thermal conduction, the vias must be plated through and solder

filled.
