20 / 39 page ![]() AD4020/AD4021/AD4022 Data Sheet Rev. B | Page 20 of 39 APPLICATIONS INFORMATION TYPICAL APPLICATION DIAGRAMS Figure 40 shows an example of the recommended connection diagram for the AD4020/AD4021/AD4022 when multiple supplies, V+ and V−, are available. This configuration is used for optimal performance because the amplifier supplies can be selected to allow the maximum signal range (see Figure 40 for the range). Figure 41 shows a recommended connection diagram when using a single-supply system. This setup is preferable when only a limited number of rails are available in the system and power dissipation is of critical importance. Figure 42 shows a typical application diagram when using a fully differential amplifier.
