DEXA Technologies Discrete Audio Op-Amp
pcX is proud to now be stocking DEXA’s “latest and greatest” op amp – the ULTIMATE EDITION.
The Ultimate Edition op amps use a new compensation circuit which is more stable, and thus can be pushed to a higher slew rate, while maintaining full unity gain stability. It is now 100 V/uS, whereas in the Special Edition version, it's 60 V/uS. The class A point is higher in the Ultimate Edition compared to the SE version, due to changes in the power supply. However, the power consumption is lower than the SE version – thus, the best of both worlds.
The resistors are now all Susumu 0.5% thin film types, 25ppm rated, for lowest noise. The input stage now uses low noise discrete transistors, whereas in the SE version, they were Darlington types – giving better control of the bias points. The trimmer for DC offset is now a real CERMET type pot, for better stability.
Initial customer reaction describes the sonic signature as more soulful compared to the SE version, and with a more relaxed top end, with improved overall resolution.
pcX is now stocking the 8-pin DIP types – however, SMD SO8 versions are available, special order.
This new Op-Amp module is drop-in compatible with:
AD712, AD8620, LF353, LM4562, LM6172, LM833, ME49720, MC1458, MC4558, NE5532, NJM2068D , NJM4558D, NJM4559D, NJM4560D, NJM4565D, NJM4580D, OP27, OP275, OPA2132, OPA2134, OPA2604, TL072, TL082, TLE2072CP etc. for duals
