MAX4122MAX4129 19-1087 Rev 1 8/97 Single/Dual/Quad, Wide-Bandwidth, Low-Power, Single-Supply Rail-to-Rail I/O Op Amps General Description Features The MAX4122MAX4129 family of operational amplifiers 5-Pin SOT23 Package (MAX4122/4) combines wide bandwidth and excellent DC accuracy with +2.7V to +6.5V Single-Supply Operation Rail-to-Rail operation at the inputs and outputs. These devices require only 650A per amplifier, and operate from Rail-to-Rail Input Common-Mode Voltage Range either a single supply (+2.7V to +6.5V) or dual supplies Rail-to-Rail Output Voltage Swing (1.35V to 3.25V) with a common-mode voltage range 5MHz Gain-Bandwidth Product (MAX4122/3/6/7/9) that extends 250mV beyond V and V . They are capa- EE CC ble of driving 250 loads. The MAX4122/MAX4123/ 25MHz Gain-Bandwidth Product (MAX4124/5/8) MAX4126/MAX4127/MAX4129 have a 5MHz gain band- 650A Quiescent Current per Amplifier width product, while the decompensated MAX4124/ 25A Shutdown Function (MAX4123/5/7) MAX4125/MAX4128 (stable at closed-looped gains of 10 or greater) have a 25MHz gain bandwidth product. In 200V Offset Voltage addition, the MAX4123/MAX4125/MAX4127 feature a No Phase Reversal for Overdriven Inputs shutdown mode in which the outputs are placed in a high-impedance state and the supply current is reduced Drive 250 Loads to only 25A per amplifier. Stable with 500pF Capacitive Loads With their rail-to-rail input common-mode range and Unity-Gain Stable (MAX4122/3/6/7/9) output swing, these amplifiers are ideal for low-voltage Stable at Gains 10V/V (MAX4124/5/8) single-supply operation. Although the minimum operat- ing voltage is specified at 2.7V, the devices typically operate down to 1.8V. In addition, low offset voltage and high speed make them the ideal signal-condition- Ordering Information ing stages for precision, low-voltage, data-acquisition systems. The MAX4122 and MAX4124 come in the PIN- MARKING space-saving 5-pin SOT23-5 package. PART TEMP. RANGE PACKAGE INFO.
