OPA209 OPA2209 OPA4209 www.ti.com SBOS426C – NOVEMBER 2008 – REVISED OCTOBER 2013 APPLICATION INFORMATION DESCRIPTION OPERATING VOLTAGE The OPA209 series of precision operational amplifiers are unity-gain stable, and free from unexpected output and phase reversal. Applications with noisy or high-impedance power supplies require decoupling capacitors placed close to the device pins. In most cases, 0.1μF capacitors are adequate. Figure 31 shows a simplified schematic of the OPA209.
PAGE 12
OPA209 OPA2209 OPA4209 SBOS426C – NOVEMBER 2008 – REVISED OCTOBER 2013 The input terminals of the OPA209 are protected from excessive differential voltage with back-to-back diodes, as shown in Figure 32. In most circuit applications, the input protection circuitry has no consequence. However, in low-gain or G = 1 circuits, fast ramping input signals can forward-bias these diodes because the output of the amplifier cannot respond rapidly enough to the input ramp.

OPA209 OPA2209 OPA4209 www.ti.com SBOS426C – NOVEMBER 2008 – REVISED OCTOBER 2013 Figure 34 illustrates both noninverting (Figure 34a) and inverting (Figure 34b) op amp circuit configurations with gain. In circuit configurations with gain, the feedback network resistors also contribute noise. The current noise of the op amp reacts with the feedback resistors to create additional noise components. The feedback resistor values can generally be chosen to make these noise sources negligible.

OPA209 OPA2209 OPA4209 SBOS426C – NOVEMBER 2008 – REVISED OCTOBER 2013 www.ti.com ELECTRICAL OVERSTRESS Designers often ask questions about the capability of an operational amplifier to withstand electrical overstress. These questions tend to focus on the device inputs, but may involve the supply voltage pins or even the output pin.

OPA209 OPA2209 OPA4209 www.ti.com SBOS426C – NOVEMBER 2008 – REVISED OCTOBER 2013 If there is an uncertainty about the ability of the supply to absorb this current, external zener diodes may be added to the supply pins as shown in Figure 35. The zener voltage must be selected such that the diode does not turn on during normal operation. However, its zener voltage should be low enough so that the zener diode conducts if the supply pin begins to rise above the safe operating supply voltage level.
