Texas Instruments (TI) announced the launch of belonging to the Burr-Brown product line, the use of e-trim technology design high-precision, high-speed 12V CMOS Operational Amplifier - OPA727. TI e-trim is a new type of fine-tuning technology to the final stage in the manufacture of offset voltage and ADG506AKR datasheet and temperature drift calibration. Which amplifier for excellent dynamic characteristics that require the application field, if the source filters, transimpedance amplifiers, audio, test equipment and ADG506AKR price and process control.
Users can use the E-trim technology in the packaging after the OPA727s offset voltage and ADG506AKR suppliers and offset voltage temperature drift to fine-tune. This technique avoids the plastic parameters occurred during the transfer, compared to conventional laser trimming method, this technique improves the accuracy. And precision bipolar amplifiers, and low-cost CMOS operational amplifiers compared, E-trim can provide better temperature offset and offset drift.
Addition, OPA727 bandwidth of 20MHz, a slew rate of 30V/us, set-up time of 600 ns, the noise is 6nV/rtHz, only 0.0003% harmonic distortion, the above characteristics is extremely suitable for driving fast 16-bit ADC.
Input common mode range extended to ground in order to achieve single-supply operation and rail output swing within 150mV control to maximize dynamic range. Turn off (OPA728) reduces quiescent current to 6μA (standard value), and using a digital ground reference pin for easy connection to a standard dual power supply applications, the logic level. OPA727 and OPA728 has passed 4V ~ 12V or ± 2V ~ ± 6V power supply full load range of the test.
OPA727 single-channel version of the shutdown function with a single-channel version of OPA728 are used MSOP-8 and 3 × 3mm DFN-8 package. Dual-channel version of OPA2727 used 3 × 3mm DFN-8 and SO-8 package. These versions of the products now available. Four-channel version of the OPA4727 will be the first quarter of 2005. All of these products specified operating range of -40 ℃ ~ +125 ℃.
1,000-piece quantities, OPA727 and OPA728 is priced at $ 1.45 minimum. When quantities of 1,000 units, OPA2727 is priced at $ 2.20. All prices are suggested retail price.
