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.
