3. DESCRIPTION
The OPA501 is one of the ultra-low-power family operational amplifiers provided by Analogy Semi. With just 240n A 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 4.2k Hz of bandwidth, the OPA501 device works rather well with equipment such as CO detectors, smoke detectors, and PIR motion detectors. In...
