The Renesas ISL24021IRT065Z-T7A is a single voltage-feedback operational amplifier with rail-to-rail output, designed for applications that need to drive significant load current — 300 mA per channel — while maintaining a 27 MHz -3dB bandwidth and a 19 V/µs slew rate. Supply range spans 4.5 V to 19 V, and the part is specified over -40°C to 85°C, suiting it for industrial control, test equipment, and LCD bias or piezo drive stages where the output stage must source or sink real current without dropping into saturation.
The ISL24021IRT065Z-T7A's 300 mA per channel changes the board-level architecture: it can drive a resistive or capacitive load directly, eliminating a separate buffer transistor or a second gain stage. That saves PCB area and reduces part count in applications like LCD VCOM drivers, piezo actuator excitation, or high-current reference buffers. The rail-to-rail output swing holds up under load — the 19 V/µs slew rate is still available into a 300 mA demand, which is unusual for a 2.2 mA quiescent part.
