Out-of-band suppression is a good indicator of the linearity performance of the device. The results in Figure 66 show over 40 dB of out-of-band suppression, which is well beyond the 35 dB requirement and indicative of the excellent linearity performance of the THS6222. Figure 66. Out-of-Band Suppression 8.3 What to Do and What Not to Do 8.3.1 Do • Include a thermal design at the beginning of the project. • Use well-terminated transmission lines for all signals. • Use solid metal layers for the power supplies. • Keep signal lines as straight as possible. • Keep the traces carrying differential signals of the same length. 8.3.2 Do Not • Do not use a lower supply voltage than necessary. • Do not use thin metal traces to supply power. • Do not treat the D1 and D2 amplifiers as independent single-ended amplifiers. 9 Power Supply Recommendations The THS6222 supports single-supply and split-supply power supplies, and balanced and unbalanced bipolar supplies. The device has a wide supply range of 8 V (–3 V to +5 V) to 32 V (±16 V). Choose power-supply voltages that allow for adequate swing on both the inputs and outputs of the amplifier to prevent affecting device performance. Operating from a single supply can have numerous advantages. With the negative supply at ground, the errors resulting from the –PSRR term can be minimized. The DGND pin provides the ground reference for the bias control pins. For applications that use split bipolar supplies, care must be taken to design within the DGND voltage specifications and must be within VS– to (VS+ – 5 V); the DGND pin must be a minimum bias of 5 V. Thus, the minimum positive supply that can be used in split-supply applications is VS+ = 5 V. The negative supply, VS–, can then be set to a voltage anywhere in between –3 V and –27 V, as per the Recommended Operating Conditions specifications. |
