MAX495

19-0265; Rev 2; 9/96 Single/Dual/Quad, Micropower, Single-Supply Rail-to-Rail Op Amps _______________General Description The dual MAX492, quad MAX494, and single MAX495 operational amplifiers combine excellent DC accuracy with rail-to-rail operation at the input and output. Since the common-mode voltage extends from VCC to VEE, the devices can operate from either a single supply (+2.7V to +6V) or split supplies (±1.35V to ±3V). Each op amp requires less than 150µA supply current. Even with this low current, the op amps are capable of driving a 1kΩ load, and the input referred voltage noise is only 25nV/√Hz. In addition, these op amps can drive loads in excess of 1nF. The precision performance of the MAX492/MAX494/ MAX495, combined with their wide input and output dynamic range, low-voltage single-supply operation, and very low supply current, makes them an ideal choice for battery-operated equipment and other low-voltage applications. The MAX492/MAX494/MAX495 are available in DIP and SO packages in the industry-standard op-amp pin configurations. The MAX495 is also available in the smallest 8-pin SO: the µMAX package. ____________________________Features o o o o o o o o o o o o o Low-Voltage Single-Supply Operation (+2.7V to +6V) Rail-to-Rail Input Common-Mode Voltage Range Rail-to-Rail Output Swing 500kHz Gain-Bandwidth Product Unity-Gain Stable 150µA Max Quiescent Current per Op Amp No Phase Reversal for Overdriven Inputs 200µV Offset Voltage High Voltage Gain (108dB) Hig...
