The low noise, low bias current input stage is ideal for high gain configurations. The LTC6091 has low input offset voltage, a rail-to-rail output stage, and can be run from a single 140V or split ±70V supplies. The LTC6091 is internally protected against overtemper- ture conditions. A thermal warning output, TFLAG, goes active when the die temperature approaches 150°C. The output stage can be turned off with the output disable pin OD. By tying the OD pin to the thermal warning output, the part will disable the output stage when it is out of the safe operating area. These pins easily interface to any logic family. The LTC6091 is unity-gain stable with up to a 200pF output capacitor. A wide input and output common mode range along with many features makes the LTC6091 useful for many high voltage applications. High Voltage Analog MUX VOUT vs Time

Exposure to any Absolute Maximum Rating condition for extended periods may affect device reliability and lifetime. Note 2: Either output (OUTA or OUTB) of the LTC6091 is capable of producing peak output currents in excess of 50mA. Current density limitations within the IC require the continuous RMS current supplied by either output (sourcing or sinking) over the operating lifetime of the part to be limited to under 50mA (absolute maximum). Proper heat sinking may be required to keep the junction temperature below the absolute maximum rating. Refer to the Power Dissipation and Thermal Considerations section of the data sheet for more information. Note 3: The LTC6091I is guaranteed functional over the operating junction temperature range –40°C to 85°C. The LTC6091H is guaranteed functional over the operating junction temperature range –40°C to 125°C. Specifying the junction temperature range as an operating condition is applicable for devices with potentially significant quiescent power dissipation. Note 4:The LTC6091I is guaranteed to meet specified performance from –40°C to 85°C. The LTC6091H is guaranteed to meet specified performance from –40°C to 125°C. Note 5: This device includes overtemperature protection that is intended to protect the device during momentary overload conditions. Operation above the specified maximum operating junction temperature is not recommended. Note 6: Input bias and offset current is production tested with ±15V supplies. See Typical Performance Characteristics curves of actual typical performance over full supply range.

6091faFor more information www.linear .com/L TC6091 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.
