Typical Operating Characteristics (continued)

(VCC = +5V, VEE = -5V, VLP = +2.5V, VLM = -2.5V, DGND = 0, RXIN1+ = RXIN2+ = 0, IN1+ = IN2+ = 0, RL = 16

Ω is connected from

OUT1 to OUT2, SHDN = 0, TA = +25°C, unless otherwise noted. Preamp configured for AV = +1 with 1k

Ω from RXOUT_- to RXIN_-.

Receiver configured for AV = +1 with 1k

Ω from POUT_ to IN_-.)
