0.1-1Gs/s Dual Track-and-Hold, TH720

0.1-1Gsps Dual-Stage Differential Track-and-Hold
TH720
PRODUCT DESCRIPTION
TH720 is a dual-stage differential Track-and-Hold amplifier with independent clock
inputs. TH720 is able to sample 1 GHz signal with 12 bits of resolution, making it an
ideal solution for high-speed high-resolution data acquisition systems like
instrumentation, radio, radar, tester, etc.

KEY FEATURES• 1.5 GHz large- and small-signal bandwidth• 100-1000 MHz sampling rate
• -82 dB THD (50MHz 250mVp-p input 100Msps)• -77 dB THD (500MHz 250mVp-p input 100Msps)• -74 dB THD (1GHz 250mVp-p input 100Msps)• < 200 ps rise/fall time (20-80%)• Adjustable output common mode voltage• Independent track mode enable on both stages• Dual +5V and –5.2V power supplies• Plastic 5x5mm 32-pin QFN package• 1.5W

TYPICAL CONNECTION DIAGRAM

Description:
The measurements in the TH720 data sheet were taken using the setup above. First, connect the output OP
to a spectrum analyzer and output ON to an oscilloscope. Then, connect the differential analog input to IP
and IN. Connect the clock frequency to CK1P and CK2N. Terminate the unconnected SMA connectors
with a 50Ω termination caps. After the SMA connections are properly made, connect power supply outputs
to the corresponding DC pins without turning on the power. When ready to use, supply a DC voltage of+5.0V to VCC, +2.0V to VTO, and –5.2V to VEE.
Notes:-Using appropriate band-pass filters for the input signal may improve performance.
