Op-amps raise audio performance without increasing BOM costs

Diodes Incorporated is meeting demands for higher performance audio without an increase in BOM cost by introducing dual channel op-amps that offer a low input noise performance of 8 nV/√Hz at 1 kHz.

The performance, coupled with a wide unity gain bandwidth of 3 MHz, makes the APX4558 op-amps well suited to a broad range of cost-sensitive audio products including set top boxes and pre-amplifiers.

Two variants are being offered by Diodes, the commercial grade APX4558 with an operating temperature range of 0 to 70°C and the industrial grade APX4558I, operating from -40 up to 105°C. Both new parts are provided in the SO8 package and are pin-for-pin compatible with industry standard op-amp alternatives.

The op-amps are short-circuit protected and the devices' internal compensation delivers stability that removes the need for additional external frequency compensation components.

The parts are priced at $0.08 each in 1k quantities.
