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.
