Data Sheet
ISL55190, ISL55290
March 30, 2007
FN6262.1
Single and Dual Ultra-Low Noise, Ultra-Low
Distortion, Low Power Op Amp
The ISL55190 and ISL55290 are single and dual high speed
operational amplifiers featuring low noise, low distortion, and
rail-to-rail output drive capability. They are designed to
operate with single and dual supplies from +5VDC
(±2.5VDC) down to +3VDC (±1.5VDC). These amplifiers
draw 16mA of quiescent supply current per amplifier. For
power conservation, this family offers a low-power shutdown
mode that reduces supply current to 21µA and places the
amplifiers' output into a high impedance state. The ISL55190
ENABLE logic places the device in the shutdown mode with
EN = 0 and the ISL55290 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
common mode voltage range includes ground. The
ISL55190 and ISL55290 are stable at gains as low as 5 with
an input referred noise voltage of 1.2nV/√Hz and harmonic
distortion products -95dBc (2nd) and -92dBc (3rd) below a
4MHz 2VP-P signal.
The ISL55190 is available in space-saving 8 Ld DFN and 8 Ld
SOIC packages. The ISL55290 is available in a 10 Ld MSOP
package.
