DESCRIPTION
The THS770006 is a fixed-gain of +6dB, wideband,
fully-differential amplifier designed and optimized
specifically for driving 16-bit analog-to-digital
converters (ADCs) at input frequencies up to
130MHz, and 14-bit ADCs at input frequencies up to
200MHz. This device provides high bandwidth,
high-voltage output with low distortion and low noise,
critical in high-speed data acquisition systems that
require very high dynamic range, such as wireless
base stations and test and measurement
applications. This device also makes an excellent
differential amplifier for general-purpose, high-speed
differential signal chain and short line driver
applications.
The THS770006 operates on a nominal +5V single
supply, offers very fast, 7.5ns maximum recovery
time from overdrive conditions, and has a
power-down mode for power saving. The THS770006
is offered in a Pb-free (RoHS compliant) and green,
QFN-24 thermally-enhanced package. It is
characterized for operation over the industrial
temperature range of –40°C to +85°C.
