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 21A 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. By Intersil Corporation
