8.3.2 Power-Down Control Pin (PD)

The THS4541-DIE includes a power-down control pin, PD. This pin must be asserted high for correct amplifier operation. The PD pin cannot be floated because there is no internal pullup or pulldown resistor on this pin to reduce disabled power consumption. Asserting this pin low (within 0.7 V of the negative supply) puts the THS4541-DIE into a very low quiescent state (approximately 2 µA). Switches in the default Vocm resistor string open to eliminate the fixed bias current (25 µA) across the supply in this 200-kΩ voltage divider to mid-supply.
