LM8272: - single channel equivalent

MarkoAnte

Part Number: LM8272
Other Parts Discussed in Thread: LM8261, LM7321

Hi,

we are currently using LM8272 to buffer (from ADC) and drive (2 differential op amps) Vcom. In this design I'm using only 1 output of the LM8272 to drive both the op amps. I want to fit the entire circuit inside a tuner box (shielded box) and I'm running out of space. The circuit was already testes with LM8272 and it works.

Do you offer a single channel version of this chip? What would be a (smaller) single channel op amp?

Best regards,

Marko

HI Marko,

LM7321 and LM8261 are the closest parts in a single channel to LM8272. They come in SOT-23-5 package.

8 Pin VSSOP package is 3.00L x 3.00W x 0.97H mm, 0.65mm pitch and

5 Pin SOT-23-5 package is 2.90L x 1.60W x 1.20H mm, 0.95mm pitch

It will save some area. I do not know if that is enough for you.

Regards,

Sanjeev
