JAJSHC9B May 2019 – October 2021 ALM2402F-Q1
The excitation frequency is chosen based on the desired secondary-side output signal resolution. The excitation signal is similar to a sampling pulse in ADCs, with the real information being in the envelope created by the rotor. With a GBW of 1.3 MHz, the ALM2402F-Q1 has more than enough open-loop gain at 10 kHz to create negligible closed-loop gain error.
Along with GBW, the ALM2402F-Q1 has optimal THD and SR performance to achieve 10-VPP output per channel.
