Monolithic Difet (dielectrically isolated FET) construction provides an unusual combination of high-speed and accuracy. Its wide-bandwidth design minimizes dynamic errors. High slew rate and fast settling time allow accurate signal processing in pulse and data conversion applications. Wide bandwidth and low distortion minimize AC errors. All specifications are rated with a 1kΩ resistor in parallel with 500pF load. The OPA602 is unity-gain stable and easily drives capacitive loads up to 1500pF. (7) –In (2) +In (3) Cascode Output (6) Laser-trimmed input circuitry provides offset voltage and drift performance normally associated with precision bipolar op amps. Difet construction achieves extremely low input bias currents (1pA max) without compromising input voltage noise. The OPA602’s unique input cascode circuitry maintains low input bias current and precise input characteristics over its full input common-mode voltage range. –VS (4) (1) Difet® Burr-Brown Corp.

Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

However, as with any high-speed, wide bandwidth circuitry, careful circuit layout will ensure best performance. Make short, direct interconnections and avoid stray wiring capacitance— especially at the inverting input pin. Leakage currents across printed circuit boards can easily exceed the input bias current of the OPA602. A circuit board “guard” pattern, as shown in Figure 1, is an effective solution to difficult leakage problems. This guard pattern must be repeated on all layers of a multilayer board. By surrounding critical high impedance input circuitry with a low impedance circuit connection at the same potential, leakage currents will flow harmlessly to the low-impedance node. Power supplies should be bypassed with good high-frequency capacitors positioned close to the op amp pins. In most cases 0.1µF ceramic capacitors are adequate. Applications with heavier loads and fast transient waveforms may benefit from use of additional 1.0µF tantalum bypass capacitors. Input bias current may also be degraded by improper handling or cleaning. Contamination from handling parts and circuit boards may be cleaned with appropriate solvents and deionized water. Each rinsing operation should be followed by a 30-minute bake at +85°C.
