ISMAX = Maximum Supply Current Per Amplifier
VOUT = Maximum Output Voltage of the Application
RL = Load Resistance tied to Ground
If we set the two PDMAX equations equal to each other,
we can solve for RL:
Assuming worst case conditions of TA = +85°C, Vout =
VS/2 V, VS = 5.5V, and ISMAX = 8.8mA per amplifier,
below is a table of all packages and the minimum RL
allowed.
EL5144C Series Comparator Application
The EL5144C series amplifier can be used as a very fast,
single supply comparator. Most op amps used as a com-
parator allow only slow speed operation because of
output saturation issues. The EL5144C series amplifier
doesn’t suffer from output saturation issues. Figure 3
shows the amplifier implemented as a comparator. Fig-
ure 4 is a graph of propagation delay vs. overdrive as a
square wave is presented at the input of the comparator.
Multiplexing with the EL5144C Series
Amplifier
Besides normal power down usage, the CE (Chip
Enable) pin on the EL5146C and EL5246C series ampli-
fiers also allow for multiplexing applications. Figure 5
shows an EL5246C with its outputs tied together, driv-
ing a back terminated 75
video load. A 3 Vp-p 10 MHz
sine wave is applied at Amp A input, and a 2.4 Vp-p 5
MHz square wave to Amp B.
Figure 6 shows the
SELECT signal that is applied, and the resulting output
waveform at VOUT. Observe the break-before-make
operation of the multiplexing. Amp A is on and VIN1 is
being passed through to the output of the amplifier. Then
Amp A turns off in about 10 nsec. The output decays to
