OPA503ASOT235

The OPA503/OPA504 is one of the ultra-low-power operational amplifiers provided by Analogy. The quiescent current of the OPA503/OPA504 operational amplifiers is as low as 570 nA, and the operating voltage ranges from 1.6 V to 5.5 V, making them suitable for most battery-powered environments and able to maintain stability without the need for additional boost topologies.The OPA503/OPA504 devices maintain low power consumption and an 11 kHz bandwidth, which allows them to work well with devices such as CO detectors, smoke detectors, and PIR motion detectors. In addition, the OPA503/OPA504 operational amplifiers feature a CMOS input stage, with bias currents typically in the femtoamp range.EMI protection is incorporated within the design of the OPA503/OPA504, 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. In low-power applications, the EN pin can help save power consumption.The OPA503/OPA504 operational amplifiers are available in SOT23-5 and SOT23-6 packages, with a rated temperature range of -40°C to 125°C, making them suitable for various harsh environments.
