OPA689MMilitary wideband, high gain voltage limiting amplifier | Amplifiers | 1 | Active | The OPA689 is a wideband, voltage-feedback operational amplifier that offers bipolar output voltage limiting, and is stable for gains ≥4. Two buffered limiting voltages take control of the output when it attempts to drive beyond these limits. This new output limiting architecture holds the limiter offset error to ±15 mV. The operational amplifier operates linearly to within 30 mV of the limits.
The combination of narrow nonlinear range and low limiting offset allows the limiting voltages to be set within 100 mV of the desired linear output range. A fast 2.4-ns recovery from limiting ensures that overdrive signals are transparent to the signal channel. Implementing the limiting function at the output, as opposed to the input, gives the specified limiting accuracy for any gain, and allows the OPA689 to be used in all standard operational amplifier applications.
Nonlinear analog signal processing circuits benefit from the OPA689's sharp transition from linear operation to output limiting. The quick recovery time supports high-speed applications.
The OPA689M is available in an industry-standard pinout in a CDIP-8 package. For lower gain applications requiring output limiting with fast recovery, consider the OPA688M.

OPA690Wideband voltage-feedback operational amplifier with disable | Integrated Circuits (ICs) | 5 | Active | The OPA690 device represents a major step forward in unity-gain stable, voltage-feedback op amps. A new input architecture provides slew rate and full-power bandwidth previously found only in wide-band, current-feedback op amps. A new output stage architecture delivers 215mA of current with a minimal headroom requirement. These capabilities combine to give exceptional slew rate of 1900V/µs into a 100Ω load. The ultra-fast settling time of 13ns makes the OPA690 an excellent choice for fast sampling systems such as high-speed ADC drivers, high-speed imaging systems, and current DAC transimpedance amplifier.
The low quiescent current of 6.1mA makes the OPA690 an excellent choice in portable or battery-powered application. System power can be reduced further using the optional disable control pin (DIS). Leaving DIS open, or holding DIS high, operates the OPA690 normally. If DIS is pulled low, the OPA690 supply current drops to less than 100µA while the output goes to a high-impedance state.

OPA691Wideband Current Feedback Operational Amplifier with Disable | Amplifiers | 6 | Active | The OPA691 sets a new level of performance for broadband current feedback op amps. Operating on a very low 5.1mA supply current, the OPA691 offers a slew rate and output power normally associated with a much higher supply current. A new output stage architecture delivers a high output current with minimal voltage headroom and crossover distortion. This gives exceptional single-supply operation. Using a single +5V supply, the OPA691 can deliver a 1V to 4V output swing with over 150mA drive current and 190MHz bandwidth. This combination of features makes the OPA691 an ideal RGB line driver or single-supply Analog-to-Digital Converter (ADC) input driver.
The OPA691’s low 5.1mA supply current is precisely trimmed at 25°C. This trim, along with low drift over-temperature, ensures lower maximum supply current than competing products. System power may be further reduced by using the optional disable control pin. Leaving this disable pin open, or holding it HIGH, gives normal operation. If pulled LOW, the OPA691 supply current drops to less than 150µA while the output goes into a high impedance state. This feature may be used for power savings.

OPA694WideBand, Low-Power, Current Feedback Amplifier | Instrumentation, Op Amps, Buffer Amps | 5 | Active | The OPA694 is an ultra-wideband, low-power, current feedback operational amplifier featuring high slew rate and low differential gain/phase errors. An improved output stage provides ±80mA output drive with < 1.5V output voltage headroom. Low supply current with > 500MHz bandwidth meets the requirements of high-density video routers. Being a current feedback design, the OPA694 holds its bandwidth to very high gains—at a gain of 10, the OPA694 will still provide 200MHz bandwidth.
RF applications can use the OPA694 as a low-power SAW pre-amplifier. Extremely high 3rd-order intercept is provided through 70MHz at much lower quiescent power than many typical RF amplifiers.
The OPA694 is available in an industry-standard pinout in both SO-8 and SOT23-5 packages.
