hi,

i am new here!

i am using a tlc272. the VDD is 5V and the VOH (High-level output voltage) is 3.8V.

we need to replace the TLC272 with an other amplifier to have VOH around 4.5V

it is a simple project with no special requarments.

Giorgos,

You could consider the OPA348 family (dual is OPA2348). Output high is specified as 125mV from the rail. So for a 5k load and 5V supply, output high is 4.875V, minimum.

Regards, Bruce

thank you Bruce,

yes, that's technically possible but not acceptable in economics! the opa series has price 5 times up!

we are searching a soloution near the 0.5euros. any other ideas?

Hello Giorgos, please e-mail me direct regarding device pricing spence@ti.com

I think the OPA2348 is still a good solution.

Regards,

Keith
