Notes on Performance Curves and
Datasheet Limits
anced input is used with good input resistor matching. The
mid-level CMRR is similar to that of other single supply op
amps.
BODE PLOTS (GAIN vs FREQUENCY FOR A
The gain vs. frequency plots for a non-inverting gain of 1
show the three voltages with the 150Ω load connected in two
ways. For the single supply graphs, the load is connected to
the most negative rail, which is ground. For the split supply
graphs, the load is connected to a voltage halfway between
the two supply rails.
Numbers in parentheses are measured
fixture capacitances w/o DUT and load.

DRIVING CABLES
Pulse response curves for driving 75Ω back terminate cables
are shown for both 3V and 5V supplies. Note the good pulse
fidelity with straight 150 loads, five foot (1.5 meter) and 75
foot (22 meter) cable runs. The bandwidth is reduced when
used in a gain of ten (A
configuration, the output settles to
making this useful for amplifying small signals at a sensor or
signal source and driving a cable to the main electronics
section which may be located away from the signal source.
This will reduce noise pickup.
Please refer to Figures 1, 2, 3, 4, 5 for schematics of test
setups for cable driving.
