Dual op-amp in 8-pin DIP — 1 MHz GBW, ±15 V rails
The Texas Instruments MC1458P is a dual general-purpose operational amplifier in an 8-pin DIP package (8-DIP, 0.300" body width). Each channel delivers a 1 MHz gain-bandwidth product with a 0.5V/µs slew rate — sufficient for audio-band filtering, signal conditioning, and control-loop compensation where the signal bandwidth stays below 100 kHz. Supply range spans 10 V to 30 V total (dual ±5 V to ±15 V), so it runs from common ±12 V or ±15 V rails without a separate regulator. The 3.4 mA supply current per channel (6.8 mA total for both) keeps the thermal load low in the 8-PDIP package.
Slew rate and input offset — what they mean for the BOM
At 0.5V/µs, the output slews 5 V in 10 µs — for a 20 Vpp output swing the full-power bandwidth is about 8 kHz. That is fine for audio line-level signals, transducer amplification, or slow servo loops, but it will distort a 20 kHz sine wave at full swing. Input offset voltage is 1 mV typical (no max stated in this listing), and input bias current is 80 nA typical. For a non-inverting gain-of-10 stage with 10 kΩ source impedance, the offset error from bias current is under 1 mV — negligible against the 1 mV offset itself. Output can source or sink 25 mA per channel — enough to drive a 600 Ω load to ±15 V swing or a 2 kΩ load to ±5 V. For heavier loads (headphones, relays), buffer the output with a transistor stage.
Active production, through-hole package, ROHS3
Texas Instruments lists the MC1458P as Active with ROHS3 compliance. The 8-DIP (0.300" width, 7.62 mm pitch) through-hole package is breadboard-friendly and hand-solderable. Tube packaging means the parts ship in anti-static tubes, not tape-and-reel — factor this into pick-and-place setup if you are running a through-hole assembly line. Operating temperature range is 0°C to 70°C (commercial grade). For industrial or automotive environments requiring -40°C to +85°C or wider, look at the MC1458N or equivalent industrial-temperature variants.
