2.3.9 ALM2403-Q1

The ALM2403-Q1 is a dual-power op amp with features and performance that make this device preferable for resolver-based applications. The high-gain bandwidth and slew rate of the device, along with a continuous high-output current-drive capability, make this device an excellent choice to provide the low distortion and differential high-amplitude excitation required for exciting the resolver primary coil. Current limiting and overtemperature detection enhance overall system robustness, especially when driving analog signals over wires that are susceptible to faults.
