Hi,

I am using CY8CKIT-044 and I´ve asociated the pins P1_4 and P1_5 with the input of my opamp but I can´t find this pins in my protoboard, does anyone know why?. I add a picture of the pins diagram of my kit.

I think that it can be used by soldering the wire or external resistor.

TMP05

TMP05 doesn't seem to shut-down in hardware.

Since the OUT pin of TMP05(U1) outputs PWM according to the temperature by CONV/IN pin,

So, I think this device needs to be removed.

ello,

According to the CY8CKIT-044 demo kit schematic,

P1[4] and P1[5] are connected to PWM Temp Sensor.

Thank you for your response.

So, Can I use this pins to connect an external resistors (for example) in the inputs of my opamp?
