Features Op AmpReference • Low operating current: 450µA • Wide supply voltage range: 4V to 36V • Wide common-mode range: V - to (V+- 1.8V) • Wide differential input voltage: ±36V • Adjustable output voltage: 1.2V to 5.0V • Initial tolerance: ±2.0% • Wide operating current range: 17µA to 20mA • Tolerant of load capacitance Description The LM614 consists of four op-amps and a programmable voltage reference in a 16-pin package. The op-amp out-performs most single-supply op-amps by providing higher speed and bandwidth along with low supply current. This device was specifically designed to lower cost and board space requirements in transducer, test, measurement and data acquisition systems. Combining a stable voltage reference with four wide output swing op-amps makes the LM614 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 (1 typical), initial tolerance (2.0%), and the ability to be programmed from 1.2V to 5.0V 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. As a member of National's new Super-Block™ family, the LM614 is a space-saving monolithic alternative to a multichip solution, offering a high level of integration without sacrificing performance. Applications • Transducer bridge driver and signal processing • Process and mass flow control systems • Power supply voltage monitor • Buffered voltage references for A/D's

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
