Ultra low power video buffer/filter with power-down
  • active Active

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 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.

The TSH122 is a single operator available in a tiny SC70 plastic package for space saving.
