The THS770012 is a wideband, fully-differential amplifier, with adjustable gain range from +10dB to +13.7dB (with external components). It is 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 THS770012 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 THS770012 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.
