Dual JFET op amp for precision analog front-ends
The LT1457CN8#PBF is a dual JFET-input operational amplifier from Analog Devices' LT® series, packaged in a through-hole 8-DIP (0.300", 7.62mm). It delivers a gain bandwidth product of 1.7 MHz and a slew rate of 4V/µs — enough for audio-band filtering, data-acquisition signal conditioning, and industrial sensor buffers that need to preserve signal integrity up to a few hundred kHz. The JFET input stage keeps input bias current at 7 pA and input offset voltage at 200 µV, making it a natural fit for high-impedance sources like photodiodes, pH probes, or piezoelectric accelerometers where a bipolar op amp's nanoamp bias would swamp the signal.
Sourcing and lifecycle — active, no LTB pressure
The LT1457CN8#PBF carries an Active product status. Sourcing is through the standard independent distribution channel; availability and pricing are confirmed at quote time.
What the key ratings mean for the BOM
The 4V/µs slew rate and 1.7 MHz GBW set the usable bandwidth. The 7 pA input bias and 200 µV offset are the precision specs that matter for DC accuracy.
Package and integration — through-hole DIP
The 8-DIP (0.300", 7.62mm) body is the standard dual-in-line footprint. Through-hole mounting suits prototyping and rework.
