Hi,all

 

Please advice to me.

I am considering the reduction and variation of the quiescent current.

 

Q1

In the datasheet specification for the ADL5801,

I want to know the more details of each test condition.

 

Quiescent Current

Resistor programmable >>> what is the value of register(R10)? ,and other condition?

130(typ) 200(max)mA

 

Disable Current

ENBL pin high to disable the device >>> disable and what value of register(R10)? ,and other condition?

50(typ)mA

 

 

Q2

In the datasheet page 29,

Table 4. Suggested Values of R10 (When ENBL Pin is High)

Table 5. Suggested Values of R10 (When ENBL Pin is Low)

 

R10 (Ω)  VSET (V)  IPOS (mA) ; IPOS is the mixer supply current.

226        4.14         140    (When ENBL Pin is High)

226        4.5           160    (When ENBL Pin is Low)

 

I understand that it is the value of the IPOS only.

Value of the Quiescent Current(max) is 160mA + other current(40mA) =200mA(max)

My understanding is correct?

 

Best Regards,

sss
