Electrical Characteristics: Vs+ – Vs– = 3 V

At TA ≈ 25°C, Vocm = open (defaults midsupply), VOUT = 2 VPP, Rf = 402 Ω, Rload = 499 Ω, 50-Ω input match, G = 2 V/V,

single-ended input, differential output, and PD = +Vs, unless otherwise noted. See Figure 61 for an ac-coupled gain of a

2-V/V test circuit, and Figure 63 for a dc-coupled gain of a 2-V/V test circuit.

Test levels (all values set by characterization and simulation): (A) 100% tested at 25°C; over temperature limits by characterization and

simulation. (B) Not tested in production; limits set by characterization and simulation. (C) Typical value only for information.
