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.
300 mA output — what it means for the BOM
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.
