ZHCSEK0C November 2015 – October 2024 THS4541-Q1
PRODUCTION DATA
The THS4541-Q1 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-Q1 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 midsupply.
