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

DALLAS, USA: Texas Instruments Inc. (TI) 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.

"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 VP 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.
