LM611ATM

Product Summary

The LM611ATM is an Operational Amplifier and Adjustable Reference. It consists of a single-supply op-amp and a programmable voltage reference in one space saving 8-pin package. The op-amp out-performs most single-supply op-amps by providing higher speed and bandwidth along with low supply current. The LM611ATM was specifically designed to lower cost and board space requirements in transducer, test, measurement and data acquisition systems. Combining a stable voltage reference with a wide output swing op-amp makes the LM611ATM ideal for single supply transducers, signal conditioning and bridge driving where large common-mode signals are common. The voltage reference consists of a reliable band-gap design that maintains low dynamic output impedance (1Ω typical), excellent initial tolerance (0.6%), and the ability to be programmed from 1.2V to 6.3V via two external resistors. The voltage reference is very stable even when driving large capacitive loads, as are commonly encountered in CMOS data acquisition systems. The applications of the LM611ATM include Transducer bridge driver, Process and Mass Flow Control systems, Power supply voltage monitor, and Buffered voltage references for A/D’s.
