Op-amps for cost-sensitive audio applications
Diodes Incorporated
APX4558 dual-channel op-amps
Diodes Incorporated has launched the APX4558 dual-channel op-amps with a low input noise performance of 8nV/vHz that are suitable for audio products including set-top boxes and pre-amplifiers.
The op-amps feature a wide unity gain bandwidth of 3MHz.
Two variants are being offered by Diodes: the commercial-grade APX4558 with an operating temperature range of 0C to 70C; and the industrial-grade APX4558I, operating from -40C up 105C.
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.
