AFE882H1: Sleep mode current

Part Number: AFE882H1

Hi,

Datasheet mentioned: Low quiescent current: 180 µA (typical)

With no communication, we get 300uA current.

Can we put AFE chip to sleep through software. OR It(180uA/300uA) is what we can achieve lowest.

Hi Anurag,

Let me check this out and I will get back to you shortly.

Thank you,

Hi Anurag,

The 180 uA spec is for PVDD = 3.3 V, while IOVDD is also 3.3 V, with the DAC at zero-scale and the SPI is static.

I'm assuming your PVDD line is what you reported as 300 uA, is anything else connected to PVDD?

Thank you,
Lucas

Hi,

PVDD = 5V and IOVDD = 1.8V.

But no more software control to reduce more, right?

What is temperature variation of 180uA with temperature from -40 degree to 85 degree?
