Diodes APX4558 low-noise op amps
With a low-input noise performance of 8nV/√Hz at 1 kHz, the APX4558 dual-channel op amps from Diodes meet demands for higher-performance audio without an increase in BOM cost.
This performance, coupled with a wide unity gain bandwidth of 3 MHz, makes the op amps suitable for a broad range of cost-sensitive audio products including set top boxes and preamplifiers.
Two variants are offered, 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 are provided in the SO8 package and are pin-for-pin compatible with industry-standard op-amp alternatives.
The devices are short-circuit protected and the internal compensation delivers stability that removes the need for additional external frequency compensation components.
