Dual-Supply, Rail-to-Rail Op Amps

General Description

Features

The MAX4493/MAX4494/MAX4495 single/dual/quad

general-purpose operational amplifiers are designed

for use in systems powered with dual supplies from

±±2±5ꢀ to ±525ꢀ2 These op amps proꢁide a unity-gain

bandwidth of 5MHz with only 770µA of quiescent cur-

rent per amplifier2 The wide input common-mode range

extends from ±00mꢀ beyond the negatiꢁe rail to within

125ꢀ of the positiꢁe supply rail while the output swings

ꢀ 770µA Supply Current per Amplifier

ꢀ Operates from Dual ±±2±ꢀ5 to ±ꢀ2ꢀ5 Supplies

ꢀ ꢀMHz Gain-Bandwidth Product

ꢀ Rail-to-Rail^®Output Swing

ꢀ Input 5oltage Range Extends ±00m5 Below the

Negative Rail

within 10mꢀ (R = 100kΩ) of either rail2

ꢀ 110dB Open-Loop Gain (R = 100kΩ)

These amplifiers haꢁe excellent (110dB) open-loop

gain with ꢁery low THD+N of 0200±% (f = 1kHz)2 The

single MAX4493 is aꢁailable in a tiny 5-pin SC70 pack-

age and the dual MAX4494 is aꢁailable in the space-

saꢁing 8-pin SOT±32 The quad MAX4495 is aꢁailable in

both 14-pin TSSOP and 14-pin SO packages2 All prod-

ucts are rated at the automotiꢁe temperature range of

-40°C to +1±5°C2

ꢀ Low THD+N of 0200±% (f = 1kHz)

ꢀ No Phase Reversal for Overdriven Inputs

ꢀ Unity-Gain Stable

ꢀ Available in Space-Saving Packages
