SLOS488B – NOVEMBER 2006 – REVISED FEBRUARY 2008
These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.

modes, and charge pump activation. The charge pump generates a negative supply voltage for the output
amplifiers. This allows a 0 V bias at the outputs, eliminating the need for bulky output capacitors. The thermal
block detects faults and shuts down the device before damage occurs. The I2C register records thermal fault
conditions. The current limit block prevents the output current from getting high enough to damage the device.
The De-Pop block eliminates audible pops during power-up, power-down, and amplifier enable and disable
events.
