Intersil's New 5-Volt Low Drift pinPoint(TM) Operational Amplifier Features Industry's Highest Accuracy at High Gain and Lowest Power

MILPITAS, CA -- (MARKET WIRE) -- May 11, 2009 -- Intersil Corporation (NASDAQ: ISIL), a world leader in the design and manufacture of high-performance analog and mixed signal semiconductors, has launched the industry's most accurate 5V single-supply, precision, low-power, low-drift op amp for high gain, 16-bit and 24-bit precision applications. The new Intersil pinPoint™ ISL28133 implements advanced patented chopper-stabilized design to achieve high-gain accuracy with zero drift at extremely low power consumption.

Intersil's ISL28133 is a micro-power, zero-drift, rail-to-rail input and output operational amplifier optimized for single-supply operation from 1.65V to 5.5V. With ultra-low supply current and wide input ranges, the ISL28133 is ideal for process control or industrial equipment, portable medical systems, data acquisition products, diagnostic systems, or any applications requiring extremely high accuracy for sensor frontends with limited power consumption budgets. The ISL28133, which operates on voltages as low as 1.65V supply, is also an excellent design choice for handheld devices operating off two AA or single Li-Ion batteries.

Input offset voltage is 8µV, output noise measures just 1.1µV peak-peak, and a typical temperature drift of 20 nanovolts per degree/Celsius (nV/°C), providing maximum accuracy for signal chains in applications that require very low DC noise and high gain accuracy, such as sensor amplifier front-ends.

The ISL28133 is ideal as a sensor amp frontend for pressure, temperature and other inertial sensors. Additional applications include low Ohmic current sensing that are common in power supply and safety monitors where accuracy at high gain is critical. Offset drift is 0.075µV/oC maximum, ideal for accuracy over temperature. Low current consumption of 25µA (max) enables significant power savings for portable applications. Input bias current is 300pA maximum. This op amp operates over the extended temperature range of -40°C to +125°C.

Pricing and Availability

The ISL28133 is available in 5 Lead SOT-23; Pricing begins at $0.99 each in 1,000-piece quantities.
