Ordering number : EN2624E LA6510 Monolithic Linear IC Dual Power Operational Amplifier Overview The LA6510 is a dual power operational amplifier IC capable of delivering larger output currents than conventional operational amplifiers. The LA6510 features an on-chip current limiter and provides high voltage gain and a high common-mode rejection ratio. The LA6510 is an ideal choice for power applications such as DC servos, capstan drivers, actuator drivers, programmable power supplies and high-quality audio amplifiers.

Equivalent input noise voltage [VNI] No.2624-4/6 LA6510 Application Circuit Examples Current Limiter Circuit and Output Stage In source mode, when Q3 turns on and current flows into the load resistor, a voltage difference occurs across RSC, turning on Q1 and activating the current limiter. In sink mode, Q4 turns on to develop a voltage difference of the polarity opposite to that in the source mode across RSC, thus turning on Q2 and activating the limiter. A RSC can be use to set the maximum output current, but the maximum output current will vary slightly depending on the VBE temperature characteristics of the transistor. No.2624-5/6 LA6510 Specifications of any and all SANYO Semiconductor products described or contained herein stipulate the performance, characteristics, and functions of the described products in the independent state, and are not guarantees of the performance, characteristics, and functions of the described products as mounted in the customer's products or equipment.
