HA5025 Application Information
Optimum Feedback Resistor
plots inverting non-inverting frequency response, Figure Figure typical performance section, illustrate performance HA5025 various closed loop gain configurations. Although bandwidth dependency closed loop gain isn't severe that voltage feedback amplifier, there appreciable decrease bandwidth higher gains. This decrease minimized taking advantage current feedback amplifier's unique relationship between bandwidth current feedback amplifiers require feedback resistor, even unity gain applications, conjunction with internal compensation capacitor, sets dominant pole frequency response. Thus, amplifier's bandwidth inversely proportional HA5025 design optimized 1000 gain Decreasing unity gain application decreases stability, resulting excessive peaking overshoot. higher gains amplifier more stable, decreased trade-off stability bandwidth. following table lists recommended values various gains, expected bandwidth.

Attention must given decoupling power supplies. large value (10µF) tantalum electrolytic capacitor parallel with small value (0.1µF) chip capacitor works well most cases. ground plane strongly recommended control noise. Care must also taken minimize capacitance ground seen amplifier's inverting input (-IN). larger this capacitance, worse gain peaking, resulting pulse overshoot possible instability. recommended that ground plane removed under traces connected
