The Analog Devices LT1674IN#PBF is a quad general-purpose op-amp in a 14-pin DIP package, designed for applications where supply current is the binding constraint. Each of the four amplifiers draws a total supply current of 1.9 µA across all channels, making this part a fit for battery-powered sensor conditioning, portable instrumentation, and always-on monitoring loops where every microamp counts.
Supply range and operating conditions
The supply span runs from 2.2 V minimum to 36 V maximum, so the same part can serve a 3.3 V lithium-cell application and a 24 V industrial control board without a change in BOM. Input bias current is 25 pA typical, which is low enough for high-impedance sensor interfaces without the leakage concerns of a bipolar input stage.
Package and mounting
The LT1674IN#PBF comes in a 14-lead PDIP package with 0.300-inch body width and 2.54 mm pin pitch, the standard through-hole DIP footprint. This makes it breadboard-friendly during development and socketable in production for designs that need field replacement without desoldering. The through-hole mounting also suits legacy boards being retrofitted with a lower-power op-amp, or any assembly line that avoids surface-mount reflow.
