LM614  
Quad Operational Amplifier and Adjustable Reference  
General Description  
The LM614 consists of four op-amps and a programmable  
Features  
Op Amp  
voltage reference in  
a 16-pin package. The op-amp  
n Low operating current: 300 µA  
n Wide supply voltage range: 4V to 36V  
n Wide common-mode range: V− to (V+− 1.8V)  
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.  
±
n Wide differential input voltage:  
36V  
n Available in plastic package rated for Military  
Temperature Range Operation  
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 ref-  
erence 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 refer-  
ence is very stable even when driving large capacitive loads,  
as are commonly encountered in CMOS data acquisition  
systems.  
Reference  
n Adjustable output voltage: 1.2V to 6.3V  
n Tight initial tolerance available:  
n Wide operating current range: 17 µA to 20 mA  
n Tolerant of load capacitance  
±
0.6%  
Applications  
n Transducer bridge driver and signal processing  
n Process and mass flow control systems  
n Power supply voltage monitor  
™
As a member of National’s new Super-Block family, the  
n Buffered voltage references for A/D’s  
LM614 is a space-saving monolithic alternative to a multichip  
solution, offering a high level of integration without sacrificing  
performance.
