ISL55191, ISL55291 Single and Dual Ultra-Low Noise, Ultra-Low 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 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 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 ISL55191 ENABLE logic places the device in the shutdown mode with 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 common mode voltage range includes ground. The ISL55191 and ISL55291 are stable at gains as low as 10 with an input referred noise voltage of 1.3nV/√Hz and harmonic distortion products -94dBc (2nd) and -104dBc (3rd) below a 1MHz 2VP-P signal. The ISL55191 is available in space-saving 8 Ld DFN and 8 Ld SOIC packages. The ISL55291 is available in a 10 Ld MSOP package.
