STMicroelectronics TSH122
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. The TSH122 features a 6th-order internal reconstruction filter to attenuate the parasitic frequency of 27 MHz from the clock of the video DAC. The TSH122 operates from 2.25 to 5 V single power supplies and is tested at 2.5 V and 3.3 V.| Part No. | TSH122 |
