The OPA501 is one of the ultra-low-power family operational amplifiers provided by AnalogySemi. With just 240nA of quiescent current and operating voltage ranged between 1.6V and 5.5V, the OPA501 operational amplifier is applicable to most battery-powered circumstances and stable even without additional boost topology. Keeping low power consumption and 4.2kHz of bandwidth, the OPA501 device works rather well with equipment such as CO detectors, smoke detectors, and PIR motion detectors. In addition, the OPA501 operational amplifier has CMOS input stages with typically femto-amp bias currents. EMI protection is incorporated into the OPA501 design in order to enhance overall system reliability by reducing system sensitivity to undesirable RF signals from mobile phones, Wi-Fi, radio transmitters, and tag readers.
The OPA501 operational amplifier is offered in the SOT23-5 package and specified from –40°C to 125°C, which makes it suitable for various rugged environment.
