These devices consume only ♦ Rail-to-Rail Input Common-Mode Voltage Range 650µA per amplifier and operate from either a single sup- ♦ Rail-to-Rail Output Voltage Swing ply (2.4V to 6.5V) or dual supplies (±1.2V to ±3.25V). These unity-gain-stable amplifiers are capable of driving 250Ω ♦ 5MHz Gain-Bandwidth Product loads and have a 5MHz gain-bandwidth product. The ♦ 650µA Quiescent Current per Amplifier MAX4323 and MAX4327 feature a low-power shutdown mode that reduces supply current to 25µA and places the ♦ 700µV Offset Voltage outputs in a high-impedance state. ♦ No Phase Reversal for Overdriven Inputs With their rail-to-rail input common-mode range and ♦ Drive 250 Ω Loads output swing, these amplifiers are ideal for low-voltage, single-supply operation. In addition, low offset voltage ♦ 25µA Shutdown Mode (MAX4323/MAX4327) and high speed make them the ideal signal-condition- ♦ Unity-Gain Stable for Capacitive Loads ing stages for precision, low-voltage data-acquisition Up to 500pF systems. The MAX4323 is offered in a small 6-bump chip-scale package (UCSP™). The MAX4322/MAX4323 are also Ordering Information available in space-saving SOT23 packages.
