Teknik Özellikler
Part Number Definition
LT1818 is a single wide bandwidth voltage feedback operational amplifier featuring fast slew rate and low harmonic distortion. CS5 indicates commercial temperature range and 5-lead TSOT-23 surface mount package. This component is delivered in lead-free tape-and-reel form to support automated high-volume SMT assembly.
Core Electrical Performance Parameters
Built with bipolar semiconductor technology, this operational amplifier retains the precise DC performance of voltage-feedback amplifiers while offering extremely rapid transient response ideal for high-frequency analog signal processing.
The amplifier has a 400 MHz gain bandwidth product and a slew rate of 2500 V/μs, allowing it to track fast changing step signals without waveform distortion. Each channel consumes 9 mA quiescent supply current during normal operation. Input referred voltage noise is 6 nV per root hertz at 1 kilohertz, and maximum input offset voltage is limited to 1.5 mV with mild temperature drift. Total harmonic distortion reaches -85 dBc at 5 MHz, ensuring pure output for high-frequency waveforms.
The device is unity gain stable and can directly drive 20 pF capacitive loads without extra compensation components. Its output stage supplies up to 40 mA peak current, enough to drive transmission lines and analog-to-digital converter input terminals. It works well with dual ±5 V bipolar supplies or single 5 V power rails. Strong common-mode rejection and power supply rejection effectively block power ripple and external electromagnetic noise inside wideband circuits.
Packaging and Assembly Specifications
Packaged in tiny 5-pin TSOT-23 plastic housing with minimal overall dimensions, designed for compact portable electronics, wireless communication modules and miniature signal processing boards with restricted PCB space. Moisture Sensitivity Level is MSL1, so no waiting period is required for reflow soldering once the sealed package is opened. Standard continuous tape reels enable seamless feeding for automated placement machines throughout mass production runs.
Environmental and Compliance Standards
The commercial version operates steadily between 0 °C and 70 °C, while industrial versions maintain reliable performance from -40 °C to 85 °C. Produced using lead-free manufacturing workflows, the part conforms to global RoHS requirements. The small single-channel package cuts down PCB occupation area and streamlines the design workflow for high-speed analog front-end circuits.
