Description

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.

The small HTSSOP package with thermal pad and low RθJA allows high currents to be delivered to loads while minimizing board space. The higher gain bandwidth of the ALM2403-Q1 allows the device to be configured as a filter stage while still providing high output drive, thus significantly reducing the total solution size of a resolver drive signal chain. This reduced solution size is a key advantage offered by the ALM2403-Q1 when used in automotive and industrial applications.
