What this dual op-amp brings to the board
The Texas Instruments TLE2142CP is a dual-channel general-purpose op-amp in an 8-pin DIP through-hole package. It delivers a 5.9 MHz gain-bandwidth product and a 45 V/µs slew rate — fast enough for audio signal conditioning, active filters, and sensor front-ends that need clean transient response without the cost of a high-speed amplifier. The rail-to-rail output stage gives you the full supply swing on a single 4 V to 44 V rail, which simplifies design in single-supply industrial control cards and bench instruments. Supply draw is 6.9 mA per channel, and each output can source or sink 50 mA. The commercial temperature range (0°C to 70°C) suits indoor equipment, lab gear, and production test fixtures.
