HA-4741 is a quad operational amplifier produced by Broadcom Semiconductor. Its open-loop gain is as high as 3.5MHz, which can be used in applications such as audio amplifiers that require amplification of wideband signals
The HA-4741 is a quad operational amplifier that offers low input offset voltage (0.5 mV), low bias current (60 nA), and low input noise, with a 3.5 MHz bandwidth and 0.06 V/µs slew rate. It is suited for audio amplifiers, active filters, and battery‑powered equipment, featuring 69 dB amplifier‑to‑amplifier isolation.
The datasheet lists absolute maximum ratings, operating temperature ranges, electrical specifications, and package options (CERDIP and PDIP). It also includes typical performance curves, die dimensions, and detailed mechanical drawings for designers.
