LMV221: Variation of input level at fixed output voltage

Masanori Tachibana

Part Number: LMV221

Hello support team,

I have a question about LMV221.

[Question]
How is the variation of the input level when output voltage is 1.5 V?
Frequency of the input signal is around 400 MHz.

Customer is using LMV221 now.
The customer is studying to design such that feedback is applied when the output voltage is 1.5V.

Best regads,

Hi M. Tachibana,

I have taken measurements using the LMV211EVM. At 400 MHz input, a 1.5V output is achieve when the input power is -14.93 dBm.

Best Regards,

Dan
