Y’U’V’ in Oversampled Systems DC-Coupled Input with 150-mV Output Shift Built-in 6-dB Gain (2 V/V) +2.6-V to +5-V Single-Supply Operation Rail-to-Rail Output Allows AC or DC Output
Coupling Low Differential Gain/Phase of 0.05%/0.03В° Ultra-Small, MicrostarCSPв„ў 9-Ball Package
– Tiny PCB Area: 1,5 mm × 1,5 mm
– Very Low Profile Height: 0,45 mm (max) Fabricated using the revolutionary, complementary
Silicon-Germanium (SiGe) BiCom3X process, the
THS7319 is a very low-power, 2.6-V to 5-V
single-supply, three-channel, integrated filter video
buffer. This device is ideal for battery-powered
applications where size and power are critical
parameters. Total quiescent current is only 3.4 mA at
3.3 V and can be reduced to 0.15 ВµA while disabled. 23 The THS7319 incorporates three enhanced definition
(ED) filter channels with third-order Butterworth
characteristics. These filters are useful as
digital-to-analog converter (DAC) reconstruction filters …
