The ALD310702 from Advanced Linear Devices is a monolithic quad P-channel MOSFET array with unrivaled precision in temperature tracking and simplified bias circuitry. The matched pair circuit is designed for the next generation of products requiring extremely low power applications and mostly-on operation.

Key Features:

• Unmatched precision-matched gate threshold voltages of -.20V ± 0.02V, expanding I/O signal operating ranges, especially in low-voltage environments.
• Typical precise offset voltages (VOS) within 1mV, guaranteeing exceptional accuracy.
• Ultra-low minimum operating voltage (< 0.2V) and operating current (< 1nA) for optimal energy efficiency.
• Matched transconductance and output conductance, ensuring optimized performance.
• Designed for switching and amplifying applications in systems ranging from -0.40V to -8.0V (±0.20V to ±4.0V).
• Ideal for low input bias current, low input capacitance, and fast switching speeds.

Applications:

Typical application examples are differential amplifier input stages, backup power circuits, power failure detectors, sensors in security equipment and portable devices, high-side and sample-and-hold switches, discrete analog switches/multiplexers, and many other applications that require an always-available backup battery. This technology enables various industries, including energy harvesting systems, automotive, medical, transportation, robotics, and wireless products, to benefit from its self-contained power circuits and long-lasting low-power operation.
