Operating modes
Two sets of operating modes have been designed to offer the customer a broad choice of noise/power
consumption combinations:
•
Low-noise disabled (see Table 9)
•
Low-noise enabled (see Table 10)
Writing the LOW_NOISE bit in CTRL6 (25h) selects the operating mode (low-noise).
From each of these two sets, five operating modes have been designed:
•
1 High-Performance Mode: focus on low noise
•
4 Low-Power Modes: trade-off between noise and power consumption
These operating modes are selected by writing the MODE[1:0] and LP_MODE[1:0] bits in CTRL1 (20h).
