Precision dual op-amp in a through-hole DIP — still in active production
The LT1013DP is a dual, general-purpose precision operational amplifier in an 8-pin plastic DIP (8-PDIP) package. Supply range spans 5 V to 30 V.
90 µV offset and 1 MHz GBW — what these ratings mean for your signal chain
The 90 µV maximum input offset voltage is the headline precision spec. The 1 MHz gain-bandwidth product and 0.4 V/µs slew rate limit large-signal response. The 320 µA per-channel supply current is low for a precision op-amp, making this part viable for multi-channel data-acquisition boards where thermal drift and power dissipation matter. The 18 nA input bias current is bipolar-transistor territory — high-impedance sources (megaohm-range sensors) will see voltage errors from bias current flowing through the source resistance; a JFET or CMOS input stage would be a better choice for photodiode or high-Z buffer applications.
For sustaining a legacy BOM that still uses through-hole precision op-amps, this part does not trigger a last-time-buy event.
Through-hole 8-DIP — breadboard, rework, and legacy fit
It fits standard breadboards, protoboards, and socketed designs. For rework and repair technicians, this means no hot-air profile for an SOIC — a simple soldering iron and solder wick are sufficient. The package is compatible with 8-pin DIP sockets (e.g., 3M or Aries), which is common for early prototypes and field-service board swaps.
