UA741CD

UA741CD Description

The UA741CD from Texas Instruments is a general-purpose operational amplifier (op-amp) housed in an 8-SOIC surface-mount package. Designed for versatility, it operates over a 7V to 36V supply range, making it suitable for a wide array of analog circuit designs. With a 1 MHz gain bandwidth product and 0.5V/µs slew rate, it balances performance and power efficiency, drawing only 1.7mA supply current. The device features low input bias current (80nA) and 1mV input offset voltage, ensuring precision in signal conditioning applications. Its ROHS3 compliance and REACH unaffected status make it environmentally friendly, while its Last Time Buy status indicates limited availability for legacy designs.
