HPOUT_

PULLDOWN

Although bits 2:0 are independent, the final resistance from the resistor string is dictated by the lowest resistance chosen;

e.g., if HPOUT_PULLDOWN = 1011, a nominal 6-k

 pull-down resistance results even if 9.6-k resistance is also

selected.

3HPOUT_

LOAD

HP output load. Sets HP amplifier capacitive load capability. Table 3-7 gives output specifications. See Section 4.2 for

details.

0 (Default) 1 nF Mode

1 10 nF Mode

Note: The HP path must be powered down before reconfiguring this bit and repowered afterwards. See Section 4.2.2.
