NAME Enable input for Channel A: ENA biased LOW Disables Channel A output regardless of INA state, 1 ENA I ENA biased HIGH or floating Enables Channel A output, ENA allowed to float hence the pin-to-pin compatibility with UCC2732X N/C pin. Input to Channel A: Inverting Input in UCC27523, Non-Inverting Input in UCC27524, Inverting 2 INA I Input in UCC27525, OUTA held LOW if INA is unbiased or floating. 3 GND - Ground: All signals referenced to this pin. Input to Channel B: Inverting Input in UCC27523, Non-Inverting Input in UCC27524, Non-Inverting 4 INB I Input in UCC27525, 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 Enable input for Channel B: ENB biased LOW Disables Channel B output regardless of INB state, 8 ENB I ENB biased HIGH or floating Enables Channel B output, ENB allowed to float hence the pin-to-pin compatibility with UCC2732X N/C pin. Pin Functions (UCC27526) PIN I/O DESCRIPTION NO. NAME Inverting Input to Channel A: When Channel A is used in Non-Inverting configuration, connect 1 INA– I INA– to GND in order to Enable Channel A output, OUTA held LOW if INA– is unbiased or floating. Inverting Input to Channel B: When Channel B is used in Non-Inverting configuration, connect 2 INB– I 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 Non-Inverting Input to Channel B: When Channel B is used in Inverting configuration, connect 7 INB+ O INB+ to VDD in order to Enable Channel B output, OUTB held LOW if INB+ is unbiased or floating. Non-Inverting Input to Channel A: When Channel A is used in Inverting configuration, connect 8 INA+ I INA+ to VDD in order to Enable Channel A output, OUTA held LOW if INA+ is unbiased or floating.
