Driver Amplifiers Deliver Optimal Power, Bandwidth, Conversion Rate, Total Harmonic Distortion, and Accuracy Beijing, November 14, 2011 – Texas Instruments announced the highest performance-to-power ratio in the industry The latest single-channel analog-to-digital converter (ADC) driver further expands its product line of general-purpose low-power rail-to-rail output operational amplifiers. Compared to similar solutions, the OPAx836 op amp can reduce power consumption by 33%, bandwidth by more than 2 times, conversion rate by 15 times, total harmonic distortion (THD) by 40 times, and accuracy by 75%.

Steve Anderson, senior vice president of TI's high-performance analog business unit, pointed out: “Customers designing portable industrial measurement equipment previously used ultrasonic flowmeters, smart pumps, and power quality in 12-bit, 14-bit, and 16-bit high-precision SAR and ∆∑-type ADCs. Designed for high-precision applications, the OPAx836 op amps offer the highest performance-to-power ratio in the industry and support customers with ultra-low power while leveraging the performance of data converters. To the extreme level described in the datasheet, these ADC drivers help designers achieve high accuracy while extending the battery life of portable industrial and medical devices."
If customers need to further reduce the power consumption of battery-powered consumer electronics, such as cameras, laptops, and mobile phones, the OPAx835 ADC driver is equally applicable. The OPAx835 op amp consumes 60% less power than competing products and still has the best performance-to-power ratio.
Key Features and Benefits of the OPAx836 ADC Driver:
• Lowest power consumption: 1 mA per channel and 205 MHz bandwidth to extend the battery life of portable industrial, consumer, and medical applications, enabling low power SAR and ∆∑ ADCs such as ADC128S102 from ADS7945 and NS;
• Maximum performance: 205 MHz bandwidth, 560 V/us slew rate, 130 dBc THD, and 4.6 nV/rtHz noise, with the highest linearity, signal-to-noise ratio, and spurious-free dynamic range in its class for increased sensitivity and data conversion Performance
• High accuracy: A typical input offset voltage of 0.065 uV and drift of 1.1 mV per degree Celsius allow accurate measurements;
• Smallest package: 2mm x 2mm ultra-small WQFN package with integrated gain-setting resistors provides 75% board space savings over competing solutions.
Tools and support currently improve 2 evaluation boards (EVMs) for the single-channel OPA836 (OPA836IDBVEVM) and dual-channel OPA2836 (OPA2836IDGSEVM). In addition, the reference design for the OPA836 also provides ADS7945 (ADS7945EVM-PDK) and ADS7946 (ADS7946EVM-PDK).
The single-channel OPA835 (OPA835IDBVEVM) and dual-channel OPA2835 (OPA2835IDGSEVM) EVMs are now available for ordering.
In addition, the PSpice and TINA-TI Spice models and the TINA-TI reference design also apply to all 4 devices.

Street lamps, which refer to lamps and lanterns providing lighting for roads, refer to lamps and lanterns in the range of road surface lighting in traffic lighting. Street lamps are widely used in various places where lighting is needed. Fire is a history of human development, a history of pursuit of light, and the use of fire is an important milestone in the progress of human civilization. The bonfire that was ignited by the ancient ancestors was the earliest lights.
