(1) Maximum input current decreases linearly in proportion to the selected trim value, with a lower maximum value of 2.4mA occurring when the trim is 1.0×.
(2) Large capacitive loads could impact system performance.
(3) For applications requiring greater than 7mA combined TIA current, contact TI for details.
