Data Sheet
ISL55191, ISL55291
March 30, 2007
FN6263.1
Single and Dual Ultra-Low Noise, Ultra-Low
Features
Distortion, Rail-to-Rail, Low Power Op Amp
The ISL55191 and ISL55291 are single and dual high speed
operational amplifiers featuring low noise, low distortion, and
rail-to-rail output drive capability. They are designed to
• 1.3nV/√Hz input voltage noise, fO = 1kHz
• Harmonic Distortion -94dBc, -104dBc, fO = 1MHz
• Stable at gains as low as 10
operate with single and dual supplies from +5VDC
(±2.5VDC) down to +3VDC (±1.5VDC). These amplifiers
draw 6.1mA of quiescent supply current per amplifier. For
• 800MHz gain bandwidth product (AV = 10)
• 260V/µs slew rate
power conservation, this family offers a low-power shutdown
• 6.1mA supply current (21µA in disable mode)
mode that reduces supply current to 21µA and places the
amplifiers' output into a high impedance state. The ISL55191
• 800µV maximum offset voltage
ENABLE logic places the device in the shutdown mode with
• 12µA input bias current
EN = 0 and the ISL55291 is placed in the shutdown mode
with EN = 1.
These amplifiers have excellent input and output overload
recovery times and outputs that swing rail-to-rail. Their input
• 3V to 5.5V single supply voltage range
• Rail-to-rail output
• Pb-free plus anneal available (RoHS compliant)
common mode voltage range includes ground. The
ISL55191 and ISL55291 are stable at gains as low as 10
Applications
with an input referred noise voltage of 1.3nV/√Hz and
• High speed pulse applications
harmonic distortion products -94dBc (2nd) and -104dBc
(3rd) below a 1MHz 2VP-P signal.
• Low noise signal processing
• ADC buffers
The ISL55191 is available in space-saving 8 Ld DFN and 8 Ld
SOIC packages. The ISL55291 is available in a 10 Ld MSOP •www.DataSheet4U.comDAC output amplifiers
package.
• Radio systems

NOTE: Intersil Pb-free plus anneal products employ special Pb-free
material sets; molding compounds/die attach materials and 100% matte
tin plate termination finish, which are RoHS compliant and compatible
with both SnPb and Pb-free soldering operations. Intersil Pb-free
products are MSL classified at Pb-free peak reflow temperatures that
meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.
1 CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.
