6.7 Electrical Characteristics (continued)

For VS = (V+) – (V–) = 2.7 V to 40 V (±1.35 V to ±20 V) at TA = 25°C, RL = 10 kΩ connected to VS / 2, VCM = VS / 2, and VOUT

= VS / 2, unless otherwise noted.

(1)

Specified by characterization only.

(2)

At high supply voltage, placing the OPAx992-Q1 in a sudden short to mid-supply or ground leads to rapid thermal shutdown. Output

current greater than ISC can be achieved if rapid thermal shutdown is avoided as per Output Voltage Swing vs Output Current.
