... LM7131 Tiny High Speed Single Supply Operational Amplifier General Description The LM7131 is a high speed bipolar operational amplifier available in a tiny SOT23-5 package. This makes the LM7131 ideal for space and weight critical designs. Single supply voltages of 3V and 5V provides good video perfor- mance, wide bandwidth, low distortion, and high PSRR and CMRR ...

... This makes it possible to design the LM7131 into places where amplifiers could not previously fit. The LM7131 can be used to drive coils and transformers ref- erenced to virtual ground, such as magnetic tape heads and disk drive write heads. The small size of the SOT23-5 pack- age can allow placed with a pre-amp inside of some rotating helical scan video head (VCR) assemblies ...

DRIVING TYPE 1175 FLASH A/D LOADS The circuits in Figures 10, 11 show a LM7131 in a voltage follower configuration driving the passive equivalent of a typical flash A/D input. Note that there is a slight ringing on the output, which can affect accurate analog-to-digital conversion ...

... LIMITS AND PRECAUTIONS Supply Voltage The absolute maximum supply voltage which may be ap- plied to the LM7131 is 12V. Designers should not design for more than 10V nominal, and carefully check supply toler- ances under all conditions so that the voltages do not ex- ceed the maximum. ...

... This resistor will re- duce reflections on the cable. Input Current The LM7131 has typical input bias currents in the 15 µ µA range. This will not present a problem with the low in- put impedances frequently used in high frequency and video circuits ...

... LM1881 Video Sync Separator. Note: This is an illustration of a conceptual use of the LM7131, not a com- plete design. The circuit designer will need to modify this for input pro- tection, sync, and possibly some type of gain control for varying signal levels ...

... For scanners and copiers with moving scan bars, the SOT23-5 package is small enough to be placed next to the light sensor. The LM7131 can drive a cable to the main elec- tronics section from the scan bar. This can reduce noise pickup by amplifying the signal before sending on the cable. ...

... The sinking output of the LM7131 is somewhat lower than the amplifier’s sourcing capability. This means that the LM7131 will not drive as much current into a load tied to 2 will drive into a load tied to 0V. Good AC performance will require keeping the output further away from the supply rails ...

... Using the LM7131 (Continued) D/A Output Amplifier The LM7131 can be used as an output amplifier for fast digital-to-analog converters. When using the LM7131 with converters with an output voltage range which may exceed ± the differential input voltage limit of 2V, it may be necessary to add protection diodes to the inputs. See Figure 15 . For high speed applications, it may be useful to consider low ca- pacitance schottky diodes ...
