ZHCSJZ2D August 2019 – April 2021 THS6222
PRODUCTION DATA
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.
