2. Current Consumption -- current consumption

Standby mode -- standby mode

3. Infinite Impulse Response Digital Filter (Infinite Impulse Response)

Ami_sint8 ami_setiirstrength (ami_uint8 MF, ami_uint8 GF); used to set the IIR of M-sensor and M-Sensor

4. Low dropout Regulator

It is a low-voltage differential linear voltage regulator compared with the traditional linear voltage regulator. Traditional linear voltage regulators, such as 78xx series chips, require that the input voltage be 2 V higher than the output voltage ~ 3 V or above, otherwise it will not work normally. However, in some cases, such conditions are obviously too harsh. For example, the input and output pressure difference between 5 V and 3.3 V is only 1.7 V, which obviously does not meet the conditions. In this case, the power conversion chip of the ldos class is available.
5. Adi is an analog-die Interface

Such as kernel/ARCH/ARM/mach-sc8810/include/Mach/adi_hal_internal.h

Adi_analogdie_reg_write (reg_addr, (unsigned short) (value ))

Adi_analogdie_reg_read (reg_addr)

Die semantics:DieIn
The context of integrated circuits is
Small block of semiconducting material,
On which a given functional circuit is fabricated. Typically, integrated circuits are produced in large batches on a Single wafer
Electronic-grade silicon (EGS) or other
Semicondu( such as AAS) through processes
Such as photolithography. The wafer is
Cut ("diced") into Duplicate pieces, each containing one copy of the circuit. Each of these pieces is called a die.

There are three commonly used plural forms:Dice,Dies, AndDie.
