Product details

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).

Sourcing and lifecycle — active, no LTB pressure

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.

Frequently asked questions

Where can I buy LT1457CN8#PBF?

The LT1457CN8#PBF is available to order through independent semiconductor distribution. Submit an RFQ for current pricing and availability — stock levels and lead times are confirmed at quote time, not listed on the page.

Is LT1457CN8#PBF a dual op amp?

Yes, it is a dual JFET operational amplifier with two independent channels in a single 8-pin DIP package.

What are the alternative or equivalent parts to LT1457CN8#PBF?

A close functional peer is the AD712KNZ, also a dual JFET op amp in a through-hole DIP. The AD712 offers a 4 MHz GBW and 20 V/µs slew rate, but its input offset voltage is 300 µV and it is specified only for 0°C to 70°C — not the full industrial -40°C to 85°C range of the LT1457CN8#PBF. For a wider temperature range (-40°C to 125°C) and lower bias (2 pA), the ADA4062-4ARUZ is a quad surface-mount option, though its 1.4 MHz GBW and 3.3 V/µs slew rate are slightly lower. Neither is a drop-in replacement without verifying the pinout and supply voltage.

What is the pinout of LT1457CN8#PBF?

Standard 8-DIP dual op amp pinout: pin 1 = Output A, pin 2 = Inverting Input A, pin 3 = Non-Inverting Input A, pin 4 = V–, pin 5 = Non-Inverting Input B, pin 6 = Inverting Input B, pin 7 = Output B, pin 8 = V+.
