Part Number: DUAL-DIYAMP-EVM
Other Parts Discussed in Thread: TLV9052

Hello guys,

One of my customers is considering using TLV9052IDGK (VSSOP8pin) for their new products and they want to evaluate the device using DUAL-DIYAMP-EVM.

They have the following questions about DUAL-DIYAMP-EVM. Could you please give me your reply for them?

Q1. Can VSSOP8pin package be assembled to the EVM?

Q2. If Q1 answer is No, which package can be assembled to the EVM?

Q3. Is the peripheral part land pattern size for 0805 and 0603?

Can 1608 size part assembled to the EVM?

Your reply would be much appreciated.

Best regards,

Kazuya.

Hello Kazuya,

No, the DUAL-DIYAMP-EVM is only compatible with SOIC-8 package amplifiers. I recommend the customer sample TLV9052 in SOIC-8 package for the EVM, and design with VSSOP for the final board.

Only SOIC-8. The only EVM compatible with VSSOP-8 package amplifiers is the DIP-ADAPTER-EVM, however this EVM acts only as a conversion board to adapt various packages to DIP spacing.

Can 1608 size part assembled to the EVM?

1608 size components were not intended for use on the EVM. The board has footprints which facilitate 0603 and 0805 components. I would imagine 1608 would likely be too large to fit on the PCB pads.

Can the customer sample TLV9052 in SOIC-8, and use 0805 components for testing?

Please let me know if you have any questions.

Thank you,

Jacob

Hello Jacob,

Thank you very much for your reply.
Could I ask you an additional question?
Are these 0603 and 0805 components size in milli inch? Or in millimeter?

Thank you again and best regards,

Kazuya.

Hi Kazuya,

it's designed for "0603" and "0805" (EIA), which is "1608" and "2012" (JIS).

Hey Kazuya,

Kai is correct, my initial response was incorrect. I had considered 1608 to be an imperial size, it is not.

1608 will work fine on the EVM.

Sorry for the confusion.

Best,

Jacob

Hi Jacob, Kai,

Thank you very much for your replies.

Could I ask you an additional question again?
The customer wants to evaluate TLV9052 using 3.3 Inverting Amplifier board (probably type B) of the EVM user's guide.
https://www.ti.com/lit/ug/sbou193/sbou193.pdf

What size is peripheral parts (resistor and capacitor) land pattern on the board? Is it 1608(mm)?

Thank you again and best regards,

Kazuya.

Hi Kazuya,

the solder pads are so large and the pads are so close to each other that 0805 (2012) and 0603 (1608) should be able to be mounted.

And section 1 of user's guide seems to confirm what I'm saying:

"The EVM is designed for 0805 and 0603 package size surface mount components enabling easy prototyping."
