Op-Amps Aim For Audio Excellence

Addressing demands for higher audio performance without an increase in BOM costs, the APX4558 dual channel op-amps spec an input-noise performance of 8nV/√Hz at 1 kHz and a unity gain bandwidth of 3 MHz. The devices are available in two versions: the commercial grade APX4558 with an operating temperature range of 0ºC to +70ºC and industrial grade APX4558I operating from -40ºC up to +105ºC.  Both are available in SO8 packages and are pin-for-pin compatible with other industry-standard op-amps. Price is $0.08 each/1,000. DIODES INC., Dallas, TX. (972) 385-2810.
