ELECTRICAL CHARACTERISTICS: VS = +1.8V to +5.5V or ±0.9V to ±2.75V (continued)
Boldface limits apply over the specified temperature range, TA = –40°C to +125°C.
At TA = +25°C, RL = 10kΩ connected to VS/2, VCM = VS/2, VOUT = VS/2, and SHDN x = VS+, unless otherwise noted.

Specified by design and characterization; not production tested.
(4)
Disable time (tOFF) and enable time (tON) are defined as the time between the 50% point of the signal applied to the SHDN pin and the
point at which the output voltage reaches the 10% (disable) or 90% (enable) level.
(5)
Full shutdown refers to the dual OPA2320S having both A and B channels disabled (SHDN A = SHDN B = VS–). For partial shutdown,
only one SHDN pin is exercised; in this mode, the internal biasing and oscillator remain operational and the enable time is shorter.
