OP27GSZ-REEL7

OP27GSZ-REEL7 is the 7-inch-reel SOIC-8 ordering code for the Analog Devices OP27 precision operational amplifier, written word-for-word in the ordering guide of the maker’s current datasheet (Rev. F), where the Z marks the lead-free form of the G grade. Every figure here is from the OP27G row of the electrical table, at ±15 V supplies and 25 °C: an input offset voltage of 30 µV typical and 100 µV maximum, an input bias current of ±15 nA typical and ±80 nA maximum, input noise of 3.8 nV/√Hz typical and 8.0 nV/√Hz maximum at 10 Hz, a common-mode rejection of 100 dB minimum and 120 dB typical, a gain-bandwidth product of 5.0 MHz minimum and 8.0 MHz typical, and a slew rate of 1.7 V/µs minimum and 2.8 V/µs typical, over -40 °C to +85 °C. The selection point is low noise with low offset in one part: microphone and sensor preamplifiers, precision filters and data-acquisition front ends that cannot afford a chopper’s switching artifacts use the OP27 class. Selection advice: the older leaded OP27GS code is a discontinued orderable and is not this part - the GSZ code on the reel label is the lead-free form to quote, and the G-grade rows above must not be replaced by the tighter E-grade figures of the same family. Parameters verified against the Analog Devices OP27 datasheet Rev. F (ordering guide and the OP27G electrical rows).
