MAX4322:Single/Dual/Quad, Low-Cost, UCSP/SOT23, Low-Power, Rail-to-Rail I/O Op Amps

The MAX4322/MAX4323/MAX4326/MAX4327/MAX4329 family of operational amplifiers combines wide bandwidth and excellent DC accuracy with rail-to-rail operation at the inputs and outputs. These devices consume only 650µA per amplifier and operate from either a single supply (2.4V to 6.5V) or dual supplies (±1.2V to ±3.25V). These unity-gain-stable amplifiers are capable of driving 250Ω loads and have a 5MHz gain-bandwidth product. The MAX4323 and MAX4327 feature a low-power shutdown mode that reduces supply current to 25µA and places the outputs in a high-impedance state. With their rail-to-rail input common-mode range and output swing, these amplifiers are ideal for low-voltage, single-supply operation. In addition, low offset voltage and high speed make them the ideal signal-conditioning stages for precision, low-voltage data-acquisition systems. The MAX4323 is offered in a small 6-bump chip-scale package (UCSP™). The MAX4322/MAX4323 are also available in space-saving SOT23 packages.
