Rail-to-Rail Output
4.2.1
MAXIMUM OUTPUT VOLTAGE
The Maximum Output Voltage (see Figure 2-16 and
Figure 2-17) describes the output range for a given
load. For example, the output voltage swings to within
50 mV of the negative rail with a 1 k
load tied to
VDD/2.
4.2.2
OUTPUT CURRENT
Figure 4-4 shows the possible combinations of output
voltage (VOUT) and output current (IOUT), when VDD =
5.5V.
IOUT is positive when it flows out of the op amp into the
external circuit.
FIGURE 4-4:
Output Current.
4.2.3
POWER DISSIPATION
Since the output short circuit current (ISC) is specified
at ±90 mA (typical), these op amps are capable of both
delivering and dissipating significant power.
FIGURE 4-5:
Diagram for Power
Calculations.
Figure 4-5 shows the power calculations used for a sin-
gle op amp:
RSER is 0 in most applications, and can be used
to limit IOUT.
VOUT is the op amp’s output voltage.
VL is the voltage at the load.
VLG is the load’s ground point.
VSS is usually ground (0V).
The input currents are assumed to be negligible. The
currents shown in Figure 4-5 can be approximated
EQUATION 4-1:
The instantaneous op amp power (POA(t)), RSER power
(PRSER(t)) and load power (PL(t)) are calculated in
EQUATION 4-2:
The maximum op amp power, for resistive loads,
occurs when VOUT is halfway between VDD and VLG or
halfway between VSS and VLG.
EQUATION 4-3:
The maximum ambient to junction temperature rise
(
TJA) and junction temperature (TJ) can be calculated
using POAmax, ambient temperature (TA), the package
thermal resistance (
JA – found in Table 1-4), and the
number of op amps in the package (assuming equal
power dissipations), as shown in Equation 4-4:
