9 / 61 page  THS4541 www.ti.com SLOS375A – AUGUST 2014 – REVISED SEPTEMBER 2014 Electrical Characteristics: Vs+ – Vs– = 3 V (continued) 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.

Maximum drift set by distribution of a large sampling of devices. Drift is not specified by test or QA sample test.
