ISL55190, ISL55290
Single and Dual Ultra-Low Noise, Ultra-Low Distortion, Low Power Op Amp
FN6262 Rev 1.00 March 30, 2007
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.
