Dear Forum-Moderators
I received my DRV595EVM a few day ago. My plan is to drive a TEC module with a Voltage up to 26 V DC.First i measured the gain resistors R1 (100k Ohm) and R2( 20k Ohm) which are on the EVAL Board by default. Approiate to the datasheet its a gain of 26 dB. To Test I connected a potentiometer( Range: 0 to 10 Ohm) on Out + and Out-. On PVCC i put a external power suplly with 26 V DC. As IN+/IN- i put a variable Voltage from 0.5V to 5V. I though i can give 0.5 V as Input and i should have an Output with a gain of 26 dB so i expected 10 V. Unexpected the Voltage jumps to over 100V parallel measured to the poti (5 Ohm) with ah Oscilloscope. I think i miss understand somithing in generall is the gain multiplied with the PVCC or with IN+?
Best regards,
Alex
