TL082BCD

The TL082BCD from Texas Instruments is a dual-channel CMOS operational amplifier designed for low-power, precision signal conditioning. It operates from a total supply voltage of 7V to 30V and draws a typical quiescent current of 1.4mA per channel. Key electrical characteristics include a gain bandwidth product of 3MHz, a slew rate of 13V/µs, and a maximum input offset voltage of 3mV at 25°C. The device achieves a typical common-mode rejection ratio of 86dB and low input bias current of 200pA maximum, making it suitable for applications requiring high input impedance.

Noise performance is specified with a voltage noise density of 18nV/√Hz at 1kHz, and the output can source or sink 10mA typical. The input common-mode headroom extends to the positive rail (0V) and within 3V of the negative rail; output swing headroom is 1.5V to each rail. Offset drift is typically 18µV/°C.

The TL082BCD is available in SOIC-8 and PDIP-8 packages with lead-free (RoHS3 compatible) finish, though compliance verification is low confidence. It operates over the commercial temperature range of 0°C to 70°C. With its CMOS architecture and balanced AC/DC performance, this amplifier is well suited for active filters, sample-and-hold circuits, and general-purpose signal processing.
