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