programmable voltage reference in one space saving
• Low Operating Current: 300 μA (op amp)
8-pin package. The op-amp out-performs most single-
• Wide Supply Voltage Range: 4V to 36V
supply op-amps by providing higher speed and
bandwidth along with low supply current. This device

• Available in Low Cost 8-pin DIP
and data acquisition systems.
• Available in Plastic Package Rated for Military
Combining a stable voltage reference with a wide

CMOS data acquisition systems.
APPLICATIONS
As a member of TI's Super-Block family, the LM611
• Transducer Bridge Driver
is a space-saving monolithic alternative to a multi-
chip solution, offering a high level of integration
• Process and Mass Flow Control Systems
without sacrificing performance.
• Power Supply Voltage Monitor
• Buffered Voltage References for A/D's
