... SAG SAG 3 3 Description The TSH122 is a video buffer that uses a voltage feedback amplifier, with an internal gain of 6 dB, an output rail-to-rail, an internal input DC-shift and a SAG correction. A power-down function allows switching to a sleep mode with an ultra-low consumption. The TSH122 features a 6th-order internal ...

... TSH122 3 Application information 3.1 Power supply considerations Correct power supply bypassing is very important for optimizing performance in high-frequency ranges. The bypass capacitors should be placed as close as possible to the IC pins to improve high-frequency bypassing. A capacitor greater than 10 µF is necessary to minimize the distortion. For better quality bypassing, we recommend adding capacitor, also placed as close as possible to the IC pins ...
