Model 252AP Datasheet and Specifications PDF Model 252AP 990Enh-Ticha and 995FET-Ticha Mechanical Options Application Note AN-18 Height, Pin Length OPTION's and socketing dimensions for both standard product and retro-clone or vintage upgrades.
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. A variant (252AP-ULN) is also available for ultra damn low noise applications. (0.560nV/rtHz at 1kHz) Unlike the original API2520 design, the 252AP can incorporate two precision matched pair transistors as the differential input stage. A total of 4 matched devices, for ultra-ultra low noise applications. These devices are selected by the manufacturer at final test to Sonic Imagery Labs noise, Vos, Ic and Vbe matching specifications.  DC perfomance is easily a magnitude better than previous counterparts. With an offset voltage of better than ±35uV (at Av1) and input leakage better than <30nA, the Sonic Imagery Labs Model 252AP is well suited for DC coupled audio applications in which output offset errors cannot be tolerated. In
addition to the enhanced input stage, and unlike the original API2520
devices, the Sonic Imagery Labs 252AP uses precision temperature stable
power supply independent current sources. Supply independent current
sources allow the bias of the input and matched pair differential VAS
stage to remain locked at the optimum operating point regardless of
power supply voltage. Another feature not found in the original API2520 design is the addition of matched pair active current loads which gives the Model 252AP differential input and VAS stage it’s outstanding (PSRR) power supply noise rejection ratio performance. The Sonic Imagery Labs 252AP can be operated from ±10V to ±25V power supplies. The redesigned input stage circuitry provides outstanding common-mode rejection and maintains low input bias current over its wide input voltage range, minimizing distortion. The 252AP is unity-gain stable and provides outstanding dynamic behavior over a wide range of load conditions. Integrated
power transistor heatsinks coupled to a anodized aluminum enclosure
keeps the Sonic Imagery Labs 252AP operating within a wide safe
operating area (SOA) and does not suffer from Beta droop when driving
heavy loads. Each amplifier is individually fully tested and meets or
exceeds published specifications. |
