Dear TI,
Technical inquiry about the following products.
1) Problem description
- The value of 15mA output was set by using current amplifier OPAMP (OPA602) using REF200AU product.
15.3mA was measured at the time of single operation, but it was confirmed to be 10.5mA at the time of functional operation measurement.
2) Connection configuration
- REF200AU 2ch 100uA bundled together
- OPA602 (1EA), 200uA is amplified by 76.5 times and the final output is 15.3mA (actual)
- The configuration amplifying component resistors (510, 39K)
- Connection configuration relay operation time (25ms ~ 250ms)
- Connection diagra
3) Questions
- Is the current amplification output of OPA 602 1EA limited to 10mA?
- Is this the part that needs more than the relay operation time to the output of the current amplification?
- Is there any other configuration that I can configure other than the above?
