Editorial Review The Sonic Imagery Labs Model 252AP is a high performance discrete operational amplifier designed for professional audio applications and areas where ultra-low noise and low distortion is required. The 252AP is best suited for use in circuits with medium to high source impedances and with microphone input transformers with high turns ratios (> 1:4). The Model 252AP is a modern re-engineering of the classic 2520 discrete op-amp. It was designed as an enhanced higher performance upgrade replacement with a focus on superior AC and DC performance. The pinouts conform to the 2520/990 package, allowing direct replacement. The all-discrete SMT design is similar to the API2520 basic topology but has been redesigned to use an ultra-precision differential super-matched input transistor pair specifically designed to meet the requirements of ultra-low noise and ultra-low THD audio systems. These devices are selected by the manufacturer at final test to Sonic Imagery Labs noise and Vbe matching specifications. DC performance is easily a magnitude better than previous counterparts. With an offset voltage of better than ±35uV (at Av1) and input leakage better than
Features 1) Ultra Low Total Harmonic Distortion, 0.0004 THD+N @1kHz 2) Ultra Low Noise 0.9nV/rtHz 3) Ultra Low Output Offset Voltage 4) Operates over 10V to 24V supply rails 5) Particular emphasis on audio performance
