JAJSF33C August 2017 – February 2023 THS3491
PRODUCTION DATA
The THS3491 operates from a single supply or with dual supplies if the input common-mode voltage range (CMIR) has the required headroom (4.3 V) to either supply rail. Supplies must be decoupled with low inductance (often ceramic) capacitors to ground less than 0.5 inches from the device pins. TI recommends using ground planes, and as in most high-speed devices, removing ground planes close to device sensitive pins such as input pins is advisable. An optional supply decoupling capacitor across the two power supplies (for split-supply operation) improves second harmonic distortion performance.
