Quad op-amp in a through-hole DIP — what it brings to the bench or the board
The Texas Instruments TLV2635IN is a quad-channel general-purpose op-amp in a 16-pin PDIP package. It delivers a 9 MHz gain-bandwidth product with a 10 V/µs slew rate, enough to handle audio-band filtering, sensor buffering, and moderate-speed control loops without slew-rate limiting. The rail-to-rail output stage swings within millivolts of either supply rail, which is useful when driving single-supply ADCs or when the signal must reach the full supply range. Input bias current is 0.7 pA (typical), making the part suitable for high-impedance sources such as photodiode transimpedance amplifiers or pH probe buffers.
16-PDIP package — why it matters for your assembly
The TLV2635IN comes in a 16-lead PDIP (0.300-inch body width), a through-hole package that fits standard DIP sockets. This makes it a practical choice for breadboard prototypes, one-off repairs, or production runs where hand-assembly and rework are preferred over reflow. The 2.54 mm pin pitch is compatible with perfboard and stripboard layouts. No exposed thermal pad — the package relies on still-air convection, so keep total dissipation within the 28 mA per-channel output limit across all four amplifiers.
That means the part is still in regular production; no last-time-buy window has been announced.
