Register 16393 (0x4009), Record Power Management
This register manages the power consumption for the record
path. In particular, the current distribution for the mixer boosts,
ADC, front-end mixer, and PGAs can be set in one of four
modes. The four modes of operation available that affect the
performance of the device are normal operation, power saving,
enhanced performance, and extreme power saving. Normal
operation has a base current of 2.5 μA, enhanced performance
has a base current of 3 μA, power saving has a base current of
a 2 μA, and extreme power saving has a base current of 1.5 μA.
Enhanced performance offers the highest performance, but
with the trade-off of higher power consumption.
Bits[6:5], Mixer Amplifier Boost
These bits set the power mode of operation for the front-end
mixer boost. With higher AVDD1 levels, distortion may become
an issue affecting performance. Each boost level enhances the
THD + N performance at 3.3 V AVDD1.
Bits[4:3], ADC Bias Control
These bits set the bias current for the ADCs based on the mode
of operation selected.
Bits[2:1], Front-End Bias Control
These bits set the bias current for the PGAs and mixers in the
front-end record path.
