MAX74825ARTZ-R7

The MAX74825ARTZ-R7 is a FET-input operational amplifier in a 5-lead SOT-23 package, specified over -40 C to +125 C and supplied on a 3000-piece reel. Analog Devices positions this amplifier for photodiode preamplifier duty, where the FET input stage keeps input bias current low enough to convert the tiny currents from optical sensors without swamping the signal. The miniature SOT-23-5 footprint places the preamplifier immediately beside the photodiode, shortening the sensitive input trace and reducing pickup in optical receivers, light meters and proximity sensing front ends. Selection advice: the ARTZ-R7 code is the SOT-23-5 reel variant in the Rev. 0 datasheet ordering guide; because the package has only five pins, confirm the pinout and single-channel configuration against your schematic symbol before layout. Parameters verified against Analog Devices documentation.
