n Available in a 20-Lead TSSOP Package The LT®1970 is a ± 500mA power op amp 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. n The circuit operates with single or split power supplies
from 5V 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 …
