... Figure 25. THD + Noise vs. Output Amplitude (V rms) The output of the OP176 is designed to maintain low harmonic distortion while driving 600 loads with very high output swings results in higher distortion if clipping occurs. To attain low harmonic distortion with large output swings, supply voltages may be increased. Figure 26 shows the perfor- mance of the OP176 driving 600 varying from 18 volts to 20 volts ...

... Noise The voltage noise density of the OP176 is below 6 nV/ Hz from 30 Hz. This enables low noise designs to have good perfor- mance throughout the full audio range. Figure 27 shows a typical OP176 with a 1/f corner 80.0 µV FS MKR: 15.9 µ MKR: 5.4 Hz BW: Figure 27 ...

... This recovery time is impor- tant in applications where the amplifier must recover quickly after a large abnormal transient event. The circuit shown in Figure 32 was used to evaluate the OP176’s overload recovery time. The OP176 takes approximately recover to V +10 V and approximately 900 ns to recover ...

... For capacitive loads greater than 400 pF, overshoot exceeds 40% and is roughly equivalent phase margin. If the applica- tion requires the OP176 to drive loads larger than 400 pF, then external compensation should be used. Figure 37 shows a simple circuit which uses an in-the-loop compensation technique that allows the OP176 to drive any capacitive load ...

... However, rated only for higher loads, this makes driving 600 loads somewhat limited with the SSM2017 alone. A pair of OP176s are used in the circuit as a high current output buffer (U2) and a DC servo stage (U3). The OP176’s high output current drive capability ...

... OS the dc performance of this circuit is quite good and will not compromise voltage reference accuracy and/or drift. Also, the OP176 has a typical current limit can provide higher output currents when compared to a typical IC reference alone. REV Differential ADC Driver ...

... R3 several reasons: One, at audio frequencies, using an amplifier with a 10 MHz bandwidth such as the OP176, these filters 34 dB), exhibit reasonably low sensitivities for unity gain and high damping (low Q). Second, as voltage followers, they are also inherently gain accurate within their pass band ...

... OS caveat here is that the additional resistors can increase noise substantially. For example resistor generates ~ 12 nV noise and is about twice that of the OP176. These resistors can be ac bypassed to eliminate their noise using a simple shunt capacitor chosen such that its reactance (X much less than R at the lowest frequency of interest. ...
