TI unveils three families of 36-V single, dual and quad op amp

Texas Instruments Incorporated (TI) has released 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.
--The OPAx209 precision op amp series combines rail-to-rail output and low voltage noise density with wide gain bandwidth.
--The general-purpose OPAx171 family features a small package that is reported to be up to 90 percent smaller than industry-standard packaging.

The key features of OPAx140 series include:
--Offers 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 key features of OPAx209 series include:
--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 key features of OPAx171 series:
--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.
