вы даташитки на SM5865CM погуглите, поизучайте... Открою маленький секрет:
улучшение характеристик указано вот в этом абзаце:
"The I/V converter output gain can be adjusted by connecting external resistors in parallel or serial with the internal resistors. Note, however, that the internal resistance can vary from device to device by ±10%, and if external resistors are used, the output level changes depending on the difference between each resistor ratio. If the I/V converter gain is increased, a dynamic range higher even than that given in “Analog Characteristics (page 8)” can be obtained."
