2.2.1 Power Supplies

The TLV1872 has separate input and output power supplies: VCCI and VEEI for the input stage and VCCO and VEEO for the output stage. This allows for both single and split supply capabilities for the input stage with ability to level shift in the output stage. The input supply voltage range is 2.7V to 36V where as the output positive supply voltage is VEEO + 2.7V to VCCI.

VCCI, VCCO, VEEI, and VEEO supply voltages can be applied directly to the DIP headers or to the test points TP9, TP2, TP3, and TP4, respectively. Additionally VCCO and VCCI can be tied together through a 0 ohm resistor in R1.
