OPA1652 OPA1654 SBOS477 – DECEMBER 2011 www.ti.com APPLICATION INFORMATION The OPA1652 and OPA1654 are unity-gain stable, precision dual and quad op amps with very low noise. Applications with noisy or high-impedance power supplies require decoupling capacitors close to the device pins. In most cases, 0.1-μF capacitors are adequate. Figure 35 shows a simplified schematic of the OPA165x (one channel shown). OPERATING VOLTAGE The OPA165x series op amps operate from ±2.
PAGE 12
OPA1652 OPA1654 SBOS477 – DECEMBER 2011 www.ti.com The input terminals of the OPA1652 and OPA1654 are protected from excessive differential voltage with back-to-back diodes, as Figure 36 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.

OPA1652 OPA1654 SBOS477 – DECEMBER 2011 www.ti.com TOTAL HARMONIC DISTORTION MEASUREMENTS The OPA165x series op amps have excellent distortion characteristics. THD + noise is below 0.0002% (G = +1, VO = 3 VRMS, BW = 80 kHz) throughout the audio frequency range, 20 Hz to 20 kHz, with a 2-kΩ load (see Figure 7 for characteristic performance). The distortion produced by the OPA165x series op amps is below the measurement limit of many commercially available distortion analyzers.
PAGE 15
OPA1652 OPA1654 SBOS477 – DECEMBER 2011 www.ti.com POWER DISSIPATION The OPA1652 and OPA1654 series op amps are capable of driving 2-kΩ 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 OPA165x series op amps improves heat dissipation compared to conventional materials. Circuit board layout can also help minimize junction temperature rise.
