1. A method for measuring a neural response to an electrical stimulus, the method comprising:
settling measurement circuitry by connecting a sense electrode to the measurement circuitry to allow the measurement circuitry to settle to a steady state;
recovering charge on a plurality of stimulus electrodes by short circuiting each electrode of the plurality of stimulus electrodes to each other electrode of the plurality of stimulus electrodes;
applying, after settling the measurement circuitry, the electrical stimulus from the plurality of stimulus electrodes to neural tissue; and
amplifying an evoked neural response signal present at the sense electrode by connecting the sense electrode to the measurement circuitry.
