This miniature, high-precision, low quiescent current amplifier offers high-impedance inputs that have a common-mode range 100 mV beyond the rails, and rail-to-rail output that swings within 50 mV of the rails. Single or dual supplies as low as 1.8 V (±0.9 V) and up to 5.5 V (±2.75 V) can be used. This device is optimized for low-voltage, single-supply operation. The OPA2333P also features a specified maximum start-up time. Specified start-up time ensures highprecision performance after 500 μs of powering the amplifier, allowing for reliable use in d...
