Texas Instruments op amp delivers industry's lowest distortion for driving high-speed 16-bit ADCs

DALLAS, Sept. 13 /PRNewswire/ -- Texas Instruments Incorporated (TI) (NYSE: TXN) today introduced a high-linearity, low-distortion, fully-differential operational amplifier (op amp) that delivers 16-bit full-scale precision up to 200 MHz IF to maximize signal chain performance for wireless base stations, high-speed data acquisition, test and measurement, medical imaging and defense applications. 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. For more information and to order samples of the THS770006 op amp, visit www.ti.com/ths770006-pr.

"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."

Key features and benefits

• Best-in-class distortion and high linearity help designers meet the stringent sensitivity and bit-error rate (BER) requirements of emerging wireless standards, such as LTE and multi-carrier GSM.
• Seamlessly drives TI high-speed analog-to-digital converters (ADCs) – including the new 16-bit, 130-MSPS ADS5493 – with full-scale, 3-V peak-to-peak dynamic range for optimal design flexibility and signal-to-noise ratio (SNR) performance.  
• Provides fast overdrive recovery of 7.5 ns (maximum) to help minimize the impact of lost or erroneous data from jammers and blockers, resulting in improved wireless receiver signal integrity.
• Speeds time-to-market when combined with TI's complete high-speed signal chain portfolio – including high-performance multicore C6000™ DSPs, high-speed ADCs like the ADS5493 and ADS4149, and clocking solutions such as the CDCE72010 – for wireless base stations, high speed data acquisition, test and measurement, medical imaging and defense applications.
