Product Overview

The LT1970CFE#PBF is a ±500mA power Operational Amplifier with precise externally controlled current limiting. Separate control voltages program the sourcing and sinking current limit sense thresholds with 2% accuracy. Output current may be boosted by adding external power transistors. The circuit operates with single or split power supplies from 5 to 36V total supply voltage. In normal operation, the input stage supplies and the output stage supplies are connected (VCC to V+ and VEE to V-). To reduce power dissipation it is possible to power the output stage (V+, V-) from independent, lower voltage rails. The amplifier is unity-gain stable with a 3.6MHz gain bandwidth product and slews at 1.6V/µs. The current limit circuits operate with a 2MHz response between the VCSRC or VCSNK control inputs and the amplifier output. Open collector status flags signal current limit circuit activation, as well as thermal shutdown of the amplifier.
