TLV316-Q1: Linear Full Scale Range input for TLV316-Q1

Naveen Johny

Part Number: TLV316-Q1

Hi all,

What should be the linear full scale range input for TLV316-Q1 ?

I'm planning to use this Op-amp for high voltage measurement and so, I'm confused on understanding the minimum input voltage that should be provided at the non-inverting terminal of TLV316-Q1 so that the device operates in linear region. And what is its gain. Is it fixed at unity most of the times ? It would be helpful If someone could point out a reference design for high voltage measurement using TLV316-Q1.

Please consider this query ASAP.

Thank You

The common-mode voltage range covers the entire supply voltage range.

This is a general-purpose amplifier; the gain depends on how you configure the feedback.

What are the desired ranges of input and output voltages? What speed do you need?

I need to measure a DC voltage of 1050 V and expecting a voltage of 3V single ended output at the Vout of TLV316-Q1

There is no amplifier that accepts 1050 V directly at its input.

You could use a resistor voltage divider to divide the input voltage down into the amplifier's range. What load can you put on the input? What speed and accuracy do you need?

Hey Naveen,

What is your supply voltage? I see you have posted another thread, is that the design you are looking to create?

Best,
Jerry
