Part Number: TLV6001
Other Parts Discussed in Thread: OPA172, TLV172, TLV9351, OPA990, LPV511

Sir/Madam,

Can we connect +5V at V+ and -5V at V- as input power supply to TLV6001IDCKR?

Got this confusion as page 9 , under section 7 is mentioned as : VS= 1.8 V to 5 V (±0.9 V to ±2.75 V)(1)""

Request to help in clarifying this

Thanks in advance

No. The supply voltage (V_S) is the difference between the V+ and V− pins, so that would be 10 V in your case.

(There is no GND pin, so from the TLV6001's point of view, a ±2.5 V supply looks exactly the same as a 5 V supply.)

Thanks for the quick reply.

Hello Haranath,

Just wanted to add that Clemens is correct and that this is the way to understand our op amp data sheets in general, not just the TLV6001.

Regards,

Daniel

Hi Daniel,

Thanks for confirmation. One more request can you please suggest suitable single channel opamp, which has V+ (max) >= +5V, and V-(max) >= -5V with pin to pin compatible to TLV6001IDCKR.

Thanks in advance

Enter 10 V and SC70 into the search function. The TLV9351 and OPA990 are not yet available in the SC70 package. The TLV172‌/‌OPA172 do not have rail-to-rail inputs. The LPV511 has a different pinout.

Hello Haranath,

Here is what I got using the search tool referenced by Clemens.

You can get a lot more options if you choose to search all the op amps TI has, instead of just the general purpose devices. Just be sure to double check the pin-to-pin compatibility.

Regards,

Daniel
