Pin Functions (UCC27527)
| PIN | I/O | DESCRIPTION | |
|---|---|---|---|
| NUMBER | NAME | ||
| 1 | INA- | I | Inverting Input to Channel A: when Channel A is used in Non-Inverting configuration connect INA- to GND in order to Enable Channel A output, OUTA held low if INA- is unbiased or floating. |
| 2 | INB- | I | Inverting Input to Channel B: when Channel B is used in Non-Inverting configuration connect INB- to GND in order to Enable Channel B output, OUTB held low if INB- is unbiased or floating. |
| 3 | GND | – | Ground: All signals referenced to this pin. |
| 4 | OUTB | I | Output of Channel B |
| 5 | VDD | O | Bias Supply Input |
| 6 | OUTA | I | Output of Channel A |
| 7 | INB+ | O | Non-Inverting Input to Channel B: When Channel B is used in Inverting configuration connect INB+ to VDD in order to Enable Channel B output, OUTB held low if INB+ is unbiased or floating. |
| 8 | INA+ | I | Non-Inverting Input to Channel A: When Channel A is used in Inverting configuration connect INA+ to VDD in order to Enable Channel A output, OUTA held low if INA+ is unbiased or floating. |
Pin Functions (UCC27528)
| PIN | I/O | DESCRIPTION | |
|---|---|---|---|
| NUMBER | NAME | ||

| 2 | INA | I | Input to Channel A: Non-Inverting Input in UCC27528, OUTA held low if INA is unbiased or floating. |
| 3 | GND | – | Ground: All signals referenced to this pin. |
| 4 | INB | I | Input to Channel B: Non-Inverting Input in UCC27528, OUTB held low if INB is unbiased or floating. |
| 5 | OUTB | O | Output of Channel B |
| 6 | VDD | I | Bias supply input |
| 7 | OUTA | O | Output of Channel A |
| 8 | ENB | I | Enable input for Channel B: ENB biased low Disables Channel B output regardless of INB state, ENB biased high or floating Enables Channel B output, ENB allowed to float. |
