±15V ELECTRICAL CHARACTERISTICS (continued)

The following specifications apply for Supply Voltage = ±15V, VCM = 0, RL ≥ 100 kΩ and RS = 50Ω, CL open, unless otherwise

noted. Boldface limits apply for TA = TJ = TMIN to TMAX; all other limits TA = TJ = 25°C.

(1)

VIN = + or −4V at TJ = −40°C.

(2)

For the condition where the CL pin is left open the output current should not be continuous, but instead, should be limited to low duty

cycle pulse mode such that the RMS output current is less than or equal to 300 mA.
