TLV6001: TLV6001 circuit design

Jerry Hsueh

Part Number: TLV6001

Hi
1, TLV6001 Inverting input and Noninverting input are connected resistors inside the chip ? how much the resistors value?
2. Is there a recommended value for the magnification of this chip?
3. For VOS vs temperature, does the external circuit have a suggested design to improve it?

Jerry,

Because it's the weekend, I only took a quicklook at the data sheet.

1) Not sure there is a resistor. Best to assume 0 ohms.
2) What does "magnification of this chip" mean? Is it application voltage gain?
3) VOS can not be automatically eliminated. It is best not to amplify VOS if you don't need to pass the DC part of the input signal.

Hi Ronald

2. Yes, voltage gain.
3. How to reduce the effect of temperature on VOS ?
thank you

Jerry,

2) The Bandwidth is typically 1 MHz so desired gain multiplied by needed bandwidth must be less than 1MHz.
3) By this question, I believe you have a way (software offset) to cancel out room temperature Vos. If true can you do this for temperature also?

Do you have a specific gain and bandwidth (lower and upper frequency) in mind?
