Advanced Linear Devices ALD110814PCL

ALD110814/ALD110914 are high-precision monolithic quad/dual enhancement-mode N-channel MOSFETs, factory-matched using ALD's proven EPAD® CMOS technology. These devices are suited for low-voltage, small-signal applications. The ALD110814/ALD110914 MOSFETs are designed and manufactured to achieve excellent device electrical characteristics matching. Since these devices are integrated on the same monolithic die, they also exhibit outstanding temperature coefficient tracking. Each device is versatile as a circuit element and serves as a practical design building block for numerous analog applications. They are fundamental building blocks for current sources, differential amplifier input stages, transmission gates, and multiplexer applications. The ALD110814/ALD110914 devices are designed to achieve minimum offset voltage and differential thermal response, suitable for switching and amplification applications in +1.5V to +10V systems that require low input bias current, low input capacitance, and fast switching speed. The ALD110814/ALD110914 are suited for precision applications requiring very high current gain (β), such as current mirrors and current sources. The high input impedance and high DC current gain of FETs result in extremely low current loss through the control gate. DC current gain is limited by gate input leakage current, which is specified at 30pA at room temperature.
