DALLAS, Oct. 27 /PRNewswire/ -- Texas Instruments Incorporated (TI) (NYSE : TXN ) today introduced three new families of 36-V single, dual and quad operational amplifiers (op amp) with industrial precision. The OPAx140 JFET input op amp series features rail-to-rail output, as well as the lowest noise and widest supply range in its class. The OPAx209 precision op amp series combines rail-to-rail output and very low voltage noise density with wide gain bandwidth. The general-purpose OPAx171 family features the industry's smallest packages – up to 90 percent smaller than industry-standard packaging to reduce board space. For more information and to order samples, see: OPAx140 (www.ti.com/opa140-pr); OPAx209 (www.ti.com/opa209-pr); OPAx171 (www.ti.com/opa171-pr).
The OPAx140 series is the first in its class to provide rail-to-rail output and a quad-input version. It was designed for applications needing high accuracy and stability, such as high-impedance sensor signal conditioning, medical instrumentation and interfacing with precision data converters.
Key features and benefits:
- Ultra-low drift of up to 1 uV/degrees C and low offset voltage of up to 120 uV provide high accuracy and stability over the full industrial temperature range.
- 11-MHz gain bandwidth and a high slew rate of 20 V/us for use in precision data acquisition systems.
- Lowest noise in its class, 5.1 nV/rtHz at 1 kHz and low frequency noise of 250 nVpp from 0.1 Hz to 10 Hz, enabling high-sensitivity, high-resolution systems across a wide frequency range.
- Wide supply range of 4.5 V (+/- 2.25 V) to 36 V (+/- 18 V) and low quiescent current of up to 2 mA reduce power consumption by 13 percent compared to the closest competitor.
The OPAx209 series was engineered for fast, high-precision data acquisition applications, such as automated test equipment, medical instrumentation and professional audio pre-amplifiers.
Key features and benefits:
- Very low voltage noise density of 2.2 nV/rtHz and ultra-low, 0.1 Hz to 10 Hz noise of 130 nVpp maximize resolution when interfacing with data converters.
- Gain bandwidth of 18 MHz – twice that of the next closest competitor – best-in-class settling time to 16-bit accuracy or 0.0015 percent, excellent DC precision of up to 150 uV offset, and low drift over temperature for driving analog-to-digital converters (ADCs) or amplifying outputs from digital-to-analog converters (DACs).
- Fully specified over a wide single- or dual-supply range of 4.5 V (+/- 2.25 V) to 36 V (+/- 18 V), it provides the lowest minimum supply voltage in its class, along with rail-to-rail output swing, to maximize dynamic range and flexibility across designs.
The OPAx171 series provides the best combination of features to simplify general purpose op amp selection. It is a cost-effective, low-power solution for space-constrained industrial applications, such as tracking amplifiers in power modules, merchant power supplies, transducer amplifiers and battery-powered test equipment.
Key features and benefits:
- First 36-V op amp offered in SOT553 (single) and VSSOP-8 (dual) micro packages. The SOT553 measures 1.6 mm x 1.6 mm x 0.6 mm – reducing device footprint by 68 percent compared to the SOT23-5, the next smallest package available. The VSSOP-8 measures 2.3 mm x 2 mm x 0.9 mm, reducing device footprint by 78 percent compared to the SO-8.
- Easy drop-in replacement of competitive devices in existing designs. The industry-standard package of SO-8 is available for the single and dual, and the SO-14 is available for the quad.
- Fully specified over a very wide single- or dual-supply range of 2.7 V (+/-1.35 V) to 36 V (+/-18 V) with rail-to-rail input and output swing and the highest common mode rejection rate in its class of 90 dB, which maximizes the input voltage range for use with low-voltage sensor outputs.
- Low quiescent current of 475 uA per channel (typical) enables low power consumption for battery-powered operation.
