The THS3001 family operates off a single supply or with dual supplies. Choose supplies that provide for the required headroom to supply rails as specified by the common-mode range (CMR). Operating from a single supply has numerous advantages. With the negative supply at ground, the dc errors due to the –PSRR term are minimized. Decouple supplies with low inductance capacitors to ground as close to the amplifier as possible. When operating on a board with high-speed digital signals, provide isolation between digital signal noise and the analog input pins. When using a ground plane, remove the ground plane close to input sensitive pins to reduce stray parasitics that adversely impact device performance. For split-supply operation, an optional supply decoupling capacitor across the two power supplies improves second harmonic distortion performance.
