Core Product Areas

Operational Amplifiers

Gainsil operational amplifiers deliver precision performance with rail-to-rail input/output, low offset voltage, and wide bandwidth options. The portfolio includes general-purpose, precision, low-power, and high-speed variants to address diverse signal conditioning requirements. Advanced TSMC process technology enables excellent DC precision with offset voltages as low as 50μV and drift specifications under 1μV/°C. Wide supply voltage ranges (1.8V to 36V) accommodate various system architectures. Available in industry-standard packages including SOT23, SC70, MSOP, and SOIC.

Comparators

Gainsil comparators offer fast response times, low power consumption, and precision threshold detection for a wide range of applications. The portfolio includes nanopower comparators for battery-operated devices, high-speed comparators for fast-switching applications, and precision comparators with low input offset voltage. Features such as internal hysteresis, rail-to-rail input, and multiple output configurations (push-pull and open-drain) provide flexibility for various circuit designs. Propagation delays range from microseconds for ultra-low power to under 100 nanoseconds for high-speed variants.

Analog Switches

Gainsil analog switches provide low on-resistance, excellent channel matching, and wide signal bandwidth for signal routing and multiplexing applications. The portfolio includes single-pole single-throw (SPST), single-pole double-throw (SPDT), and multiplexer configurations. Advanced TSMC process technology enables on-resistance as low as 0.5Ω with minimal variation across signal range and temperature. Wide supply voltage ranges and break-before-make operation ensure reliable switching in industrial, consumer, and automotive applications. Low charge injection minimizes switching glitches in precision signal paths.

Voltage References

Gainsil voltage references provide stable, accurate voltage standards for data acquisition, power supply monitoring, and precision measurement applications. The portfolio includes shunt (two-terminal) and series (three-terminal) references with various output voltages. Low temperature drift (as low as 10ppm/°C) ensures accuracy across temperature variations. High initial accuracy (±0.1% to ±1%) minimizes calibration requirements. Low quiescent current options support battery-powered applications. Wide operating current ranges accommodate diverse application requirements from microampere bias currents to milliampere load currents.
