3 Description
The ALM2402F-Q1 is a dual-power op amp with
features and performance that make this device
preferable for resolver-based automotive 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 a low distortion and differential high amplitude
excitation required for modern resolvers. Current
limiting and overtemperature detection enhance
overall system robustness when driving analog
signals over wires that are susceptible to faults.
The ALM2402F-Q1 rail-to-rail output, enabled by the
low Rds(on) PMOS and NMOS transistors, keeps the
power dissipation low. The small HTSSOP package
with thermal pad and low RθJA allows users to
deliver high currents to loads while minimizing board
space. This minimized board space is one of the key
advantages offered by the ALM2402F-Q1 when used
in modern hybrid and electric vehicles.
The ALM2402F-Q1 maximum output voltage is
