Low Differential Gain/Phase of 0.05%/0.03°
Ultra-Small, MicrostarCSP 9-Ball Package
The THS7319 is designed for dc-coupled inputs. To
mitigate any DAC/encoder termination interaction, the
Tiny PCB Area: 1,5 mm × 1,5 mm
input impedance is a very high 2.4 M
. The 150-mV
Very Low Profile Height: 0,45 mm (max)
output level shift allows for a full sync dynamic range
at the output with a 0-V input that prevents sync
crushing. The rail-to-rail output stage supports both
