Dual CMOS rail-to-rail op-amp in 8-SOIC
The TLC4502CD is a dual-channel CMOS operational amplifier from Texas Instruments, offering rail-to-rail output swing and a gain-bandwidth product of 4.7 MHz. With a slew rate of 2.5 V/µs and an input offset voltage of just 10 µV, it is suited for precision signal conditioning in low-frequency sensor interfaces and data acquisition front-ends. The 1 pA input bias current minimizes DC errors when driving high-impedance sources like photodiodes or pH probes.
Supply range and temperature grade
Operating from a single supply spanning 4 V to 6 V, the TLC4502CD covers standard 5 V single-rail systems without a negative rail. The 0°C to 70°C temperature grade targets commercial indoor equipment — bench instruments, office peripherals, and industrial control panels where ambient stays within that band. Each channel draws 2.5 mA quiescent supply current, keeping the total for both channels at 5 mA — a reasonable budget for a multi-stage signal chain on a 5 V rail.
Package and mounting detail
Housed in an 8-SOIC package (0.154-inch body width, 3.90 mm), the TLC4502CD is a surface-mount device supplied in a tube. The SOIC-8 footprint is a standard JEDEC outline — the same land pattern used for hundreds of generic op-amps, so no board spin is needed when swapping in this part.
