This document is about ADA4505-1/ADA4505-2/ADA4505-4 product introduction, introducing the product features such as low power consumption, wide output voltage range and high common mode rejection ratio.
The ADA4505‑1, ADA4505‑2 and ADA4505‑4 are single, dual and quad micropower operational amplifiers that provide rail‑to‑rail input and output swings from a single 1.8 V to 5 V supply or dual ±0.9 V to ±2.5 V supplies. They feature very low supply current (≤10 µA per amplifier), zero input crossover distortion, low bias current and high PSRR/CMRR, making them suitable for battery‑powered sensors, medical monitors and hazard detectors.
The document lists electrical characteristics for both 1.8 V and 5 V operation, absolute maximum ratings, thermal resistance data, typical performance curves, and an ordering guide that specifies the available surface‑mount packages (SOT‑23, MSOP, TSSOP and various WLCSP options).
