Intersil’s New 5-Volt Low Drift pinPoint™ Operational Amplifier Features Industry’s Highest Accuracy at High Gain and Lowest Power
Patented ISL28133 Op Amp Technology Offers High Accuracy, Zero Drift, and Low DC Noise
making it ideal for 16-bit and 24-bit Precision Applications in Industrial and Process Control
MILPITAS, CA–May 11, 2009 – Intersil Corporation
(NASDAQ Global Select: 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™ ISIL28133 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.
