Internal Bias Current Control
The ASP chain has internally generated bias
currents that result in an operating power
consumption of nearly 400mW. By attaching a
resistor between pin 19, EX-TRESA; and pin 20,
EXTRESB; the user can reduce the power
consumption of the device. This feature is
enabled by writing a 1b to bit res of the Power
Configuration Register (0Ch). Figure 19 depicts
the power savings that can be achieved with an
external resistor at nominal clock rate (10 MHz).
An external resistance (Rext) of 39 kΩ is
recommended for optimal sensor performance.
Additional power savings can be achieved at lower
clock rates.
