Texas Instruments Announces the OPAx836 ADC Drivers
Texas Instruments expanded portfolio of general-purpose, low-power, rail-to-rail output operational amplifiers (op amps) with the introduction of new single and dual analog-to-digital converter (ADC) drivers that provide the industry’s highest performance-to-power ratio. The OPAx836 op amps use 33 percent less power than similar solutions while providing more than twice the bandwidth, 15 times faster slew rate, 40 times better total harmonic distortion (THD) and 75-percent higher precision.
For customers needing even lower power for battery-operated consumer electronics, such as cameras, notebooks and cell phones, the OPAx835 ADC drivers are also available. The OPAx835 op amps use 60-percent less power than the competition while still providing a best-in-class performance-to-power ratio.
Key features and benefits of the OPAx836 ADC drivers:
- Lowest power consumption: Extends the battery life of portable industrial, consumer and medical applications with power consumption of 1 mA per channel while providing 205 MHz of bandwidth for driving low-power SAR and delta-sigma ADCs, such as the ADS7945 and the National ADC128S102.
- Highest performance: Offers 205 MHz of bandwidth with a slew rate of 560 V/us, THD of 130 dBc and noise of 4.6 nV/rtHz to achieve the highest linearity, signal-to-noise ratio and spurious-free dynamic range in its class, resulting in enhanced sensitivity and data converter performance.
- High precision: Typical input-offset voltage of 0.065 uV and drift of 1.1 mV/degree C for accurate measurement.
- Smallest package: Ultra-small 2-mm x 2-mm WQFN package with integrated gain setting resistors reduces board space up to 75 percent, compared to the competition.
Samples and production quantities of the single-channel OPA836 and OPA835 are available in two package options: 1) a 10-pin, 2-mm x 2-mm WQFN, or 2) a 6-pin, 3-mm x 3-mm SOT23. Suggested retail pricing for 1,000 units is $0.90 for the OPA836 and $ 0.85 for the OPA835.
Samples and production quantities of the dual OPA2836 and OPA2835 are available today in three package options: 1) an 8-pin, 4-mm x 5-mm SOIC, 2) a 10-pin, 3-mm x 3-mm MSOP, or 3) a 10-pin, 2-mm x 2-mm WQFN. Suggested retail pricing for 1,000 units is $1.50 for the OPA2836 and $1.35 for the OPA2835.
