At TA = +25°C, VS = ±5V, RF = 402Ω, RL = 100Ω, and G = +5, unless otherwise noted. See Figure 1 for AC performance. NOTES: (1) Junction temperature = ambient temperature for 25 °C min/max specifications. (2) Junction temperature = ambient at low temperature limit: junction temperature = ambient +23 °C at high temperature limit for over temperature min/max specifications. (3) Test Levels: (A) 100% tested at 25°C over-temperature limits by characterization and simulation. (B) Limits set by characterization and simulation. (C) Typical value only for information. (4) Current is considered positive out- of-node. VCM is the input common-mode voltage. (5) Tested < 3dB below minimum specified CMRR at ±CMIR limits. |
