OPA1602 OPA1604 SBOS474B – APRIL 2011 – REVISED NOVEMBER 2011 www.ti.com APPLICATION INFORMATION applications do not require equal positive and negative output voltage swing. With the OPA160x series, power-supply voltages do not need to be equal. For example, the positive supply could be set to +25V with the negative supply at –5V. The OPA1602 and OPA1604 are unity-gain stable, precision dual and quad op amps with very low noise.
PAGE 11
OPA1602 OPA1604 SBOS474B – APRIL 2011 – REVISED NOVEMBER 2011 www.ti.com The input terminals of the OPA1602 and OPA1604 are protected from excessive differential voltage with back-to-back diodes, as Figure 32 illustrates. 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.

OPA1602 OPA1604 SBOS474B – APRIL 2011 – REVISED NOVEMBER 2011 www.ti.com TOTAL HARMONIC DISTORTION MEASUREMENTS The OPA160x series op amps have excellent distortion characteristics. THD + noise is below 0.00008% (G = +1, VO = 3VRMS, BW = 80kHz) throughout the audio frequency range, 20Hz to 20kHz, with a 2kΩ load (see Figure 7 for characteristic performance). The distortion produced by the OPA160x series op amps is below the measurement limit of many commercially available distortion analyzers.

OPA1602 OPA1604 SBOS474B – APRIL 2011 – REVISED NOVEMBER 2011 POWER DISSIPATION The OPA1602 and OPA1604 series op amps are capable of driving 2kΩ loads with a power-supply voltage up to ±18V and full operating temperature range. Internal power dissipation increases when operating at high supply voltages. Copper leadframe construction used in the OPA160x series op amps improves heat dissipation compared to conventional materials. Circuit board layout can also help minimize junction temperature rise.
PAGE 15
OPA1602 OPA1604 SBOS474B – APRIL 2011 – REVISED NOVEMBER 2011 www.ti.com 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 36. 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.
