TI introduces industry's fastest JFET-input amplifiers

DALLAS, Dec. 11 /PRNewswire/ -- Texas Instruments Incorporated (TI) (NYSE: TXN) today introduced the OPA653 and OPA659 JFET-input operational amplifiers, which provide a slew rate of up to 2675 V/us, three times faster than that of the nearest competitor, resulting in improved pulse response. These amplifiers combine a wideband voltage feedback amplifier with a high-impedance JFET-input stage and meet the requirements for frequency domain and FFT analysis due to their large signal bandwidth and low total harmonic distortion. See more product details at www.ti.com/opa659-pr.

Key features and benefits of the OPA653 and OPA659

    --  Best-in-class slew rate and low distortion contribute to enhanced signal
        integrity for time-domain and pulse-oriented applications.

        --  The OPA653 is a fixed gain (+2 V/V) JFET-input amplifier with a slew
            rate of 2675 V/microns and 475 MHz of large signal bandwidth (2
        --  The OPA659 is a unity gain stable JFET-input amplifier with a slew
            rate of 2550 V/ us and 575 MHz of large signal bandwidth (2 Vp-p).
        --  Third order harmonic distortion (HD3) of -60 dBc (OPA659) and -66
            dBc (OPA653) at 100 MHz ensures superior high-bandwidth linearity.
    --  Fast settling time (8 ns) and overdrive recovery (8 ns) enable excellent
        pulse response.
    --  The OPA653's ultra-low overshoot and ringing are desirable in low-noise,
        wideband, high input impedance applications such as data acquisition
        cards, high-impedance probes and oscilloscope front ends.
    --  The OPA659's 350-MHz high gain bandwidth optimizes machine vision
        applications, such as broadband photodiode transimpedance amplifiers
        used in wafer inspection equipment.
    --  Power supply voltage range of +/-3.5 V to +/- 6.4 V maximizes design
    --  These devices drive TI's 12- and 14-bit, 400-MSPS and 500-MSPS
        analog-to-digital converters including the ADS5474, ADS5463 and

Availability and pricing

The OPA653 and OPA659 devices are both available in VSON-8 or SOT23-5 packages and priced at $2.95 in 1,000-piece quantities.
