9 / 22 page LTC6091 9 6091fa For more information www.linear.com/LTC6091 PIN FUNCTIONS (A Channel/B Channel) –INA , –INB (Pin 1/Pin 5): Inverting Input Pin. Input com- mon mode range is V– + 3V to V+ – 3V. Do not exceed absolute maximum voltage range. +INA, +INB (Pin 2/Pin 6): Noninverting Input Pin. Input common mode range is V– + 3V to V+ – 3V. Do not exceed absolute maximum voltage range. V– (Pin 3, Pin 7, Exposed Pad Pin 17): Negative Supply Pin. Connect to a single V– only. Both amplifiers share a common substrate, and are not isolated from each other. Pins 3, and 7 must be electrically tied to the exposed pad (Pin 17). The exposed pad connection removes heat from the device. To achieve a low thermal resistance, connect the exposed pad to a V– power plane with as much metal land as possible (see Applications Information). TFLAGA, TFLAGB (Pin 12/ Pin 8 ): Temperature Flag Pin. The TFLAG pin is an open-drain output that sinks current when the die temperature exceeds 145°C. OUTA, OUTB (Pin 13/Pin 9): Output Pin. If this rail-to- rail output goes below V– , the ESD protection diode will forward bias. If OUT goes above V+, then output device diodes will forward bias. Avoid forward biasing the diodes on the OUT pin. Excessive current can cause damage. V+A, V+B (Pin 14/Pin 10): Positive Supply Pin. Each amplifier has an independent V+ supply. But since both amplifiers shares a common substrate, they must share the same V– supply. ODA, ODB (Pin 15/Pin 11): Output Disable Pin. Active low input disables the output stage. If left open, an internal pull-up resistor enables the amplifier. Input voltage levels are referred to the COM pin. COMA, COMB (Pin 16/Pin 4): COM Pin is used to interface OD and TFLAG pins to voltage control circuits. Tie this pin to the low voltage ground, or let it float. |
