Compared to the scalable and used with every package option, including the 5-lead Burr-Brown OPA2340UR rail-to-rail input amplifier, shown in SOT-23, providing lower offset voltages than previously achieved in Figure 54, the AD860x, shown in Figure 55, exhibits lower these small packages. offset voltage shift across the entire input common-mode range, including the transition region. The DigiTrim process is completed at the factory and does not add additional pins to the amplifier. All AD860x amplifiers are 0.7 available in standard op amp pinouts, making DigiTrim completely 0.4 transparent to the user.
