XD833 DIP-8 XL833 SOP-8 FEATURES DESCRIPTION • • • • The XDXL833 is a dual general purpose operational amplifier designed with particular emphasis on performance in audio systems. 1 2 • • • • • Wide Dynamic Range: >140dB Low Input Noise Voltage: 4.5nV/√Hz High Slew Rate: 7 V/μs (typ); 5V/μs (Min) High Gain Bandwidth: 15MHz (typ); 10MHz (Min) Wide Power Bandwidth: 120KHz Low Distortion: 0.002% Low Offset Voltage: 0.3mV Large Phase Margin: 60° Available in 8 Pin VSSOP Package This dual amplifier IC utilizes new circuit and processing techniques to deliver low noise, high speed and wide bandwidth without increasing external components or decreasing stability. The XDXL833 is internally compensated for all closed loop gains and is therefore optimized for all preamp and high level stages in PCM and HiFi systems.

Electrical Characteristics state DC and AC electrical specifications under particular test conditions which ensure specific performance limits. This assumes that the device is within the Operating Ratings. Specifications are not ensured for parameters where no limit is given, however, the typical value is a good indication of device performance. If supply voltage is less than ±15V, it is equal to supply voltage. This is the permissible value at TA ≤ 85°C.

Capacitive loads up to 50 pF will cause little change in the phase characteristics of the amplifiers and are therefore allowable. Capacitive loads greater than 50 pF must be isolated from the output. The most straightforward way to do this is to put a resistor in series with the output. This resistor will also prevent excess power dissipation if the output is accidentally shorted. Noise Measurement Circuit 833 Complete shielding is required to prevent induced pick up from external sources. Always check with oscilloscope for power line noise. Figure 25.
