OPA501BSOT235

The OPA501 is one of the ultra-low-power operational amplifiers provided by Analogy. The quiescent current of the OPA501 operational amplifier is as low as 240 nA, and the operating voltage ranges from 1.6 V to 5.5 V, making it suitable for most battery-powered environments and able to maintain stability without the need for additional boost topologies.The OPA501 device maintains low power consumption and a 4.2 kHz bandwidth, which allows it to work well with devices such as CO detectors, smoke detectors, and PIR motion detectors. In addition, the OPA501 operational amplifier features a CMOS input stage, with bias currents typically in the femtoamp range.EMI protection is incorporated within the design of the OPA501, which enhances the overall system reliability by reducing the system's sensitivity to unwanted radio frequency signals from sources like mobile phones, Wi-Fi, radio transmitters, and tag receivers. The OPA501 operational amplifier is available in a SOT23-5 package, with a rated temperature range of -40°C to 125°C, making it suitable for various harsh environments.
