L2726 is a low drop dual power operational amplifier with an output current up to 1A. It operates at low voltages and can be used with either a single supply or a split supply. It has a large common-mode and differential mode range, low input offset voltage, ground compatible inputs, low saturation voltage, and thermal shutdown. The L2726 is suitable for driving inductive loads, such as motors, and finds applications in compact-disc, VCR, automotive, etc. The high gain and high output power capability provide superior performance in any operational amplifier/power booster combination.
The L2726 is a monolithic integrated circuit in an SO‑20 package designed for power‑operational‑amplifier applications such as servo amplifiers and power supplies. It can operate from a single or split supply, supports low‑voltage operation, and includes thermal shutdown protection.
Key specifications include a supply voltage range of 4‑28 V (single) or ±2‑±14 V (split), a maximum DC output current of 1 A, an input offset voltage of 10 mV, and a gain‑bandwidth product of 1.2 MHz. Mechanical dimensions and thermal resistance data are also provided.
