Op Amp from TI drives 16 bit ADCs with very low distortion

Texas Instruments has made available a precision fully-differential operational amplifier (op amp) that delivers 16-bit full-scale precision up to 200 MHz IF. This analog IC targets telecom equipment applications such as LTE and multi-carrier GSM wireless base stations and also for high-end apps such as high-speed data acquisition, test and measurement, medical imaging and defense equipments. The THS770006 op amp has an output third-order intercept (OIP3) of 48 dBm and the lowest distortion in its class, with a third-order intermodulation distortion (IMD3) of -107 dBc at 100 MHz, at least 14 dB better than competitive amplifiers.


"The advancements we've made in the performance of the THS770006 op amp will enable greater levels of receiver dynamic range in wireless systems - a requirement for base station manufacturers to meet the adjacent channel rejection and blocker requirements of next-generation networks," said Steve Anderson, senior vice president of TI's High-Performance Analog business unit. "Our customers can have confidence knowing the THS770006 op amp will help them realize the full potential of their high-speed signal chain."

This ADC driver amp is designed to gel well with TI's fast analog-to-digital converter (ADC) 16-bit, 130-MSPS ADS5493. THS770006 offers overdrive recovery of 7.5 ns (maximum) to help minimize the impact of lost or erroneous data from jammers and blockers.
