MAX4491AKA+

The MAX4491AKA+ is a kind of dual low-cost CMOS op amp. It is availabel in 8 SOT23-8 package. Specifications for all parts are guaranteed over the automotive (-40 to +125) temperature range. It is widely used in battery-powered instruments, portable equipment, audio signal conditioning, low-power/low-voltage applications, sensor amplifiers, RF power amplifier control and high-side/low-side current sensors.

There are some features as follows: (1) +2.7 V to +5.5 V single-supply operation; (2) 10 V/s slew rate; (3) rail-to-rail input common-mode voltage range; (4) rail-to-rail output voltage swing; (5) 10 MHz gain-bandwidth product; (6) unity-gain stable with capacitive loads up to 300 pF; (7) 50 pA input bias current.

What comes next is about the absolute maximum ratings. (1): supply voltage (VDD to VSS) is +6 V; (2): all other pins is from VSS-0.3 to VDD+0.3 V; (3): output short-circuit duration is 10 sec; (4): continuous power dissipation (TA=+70) is 421 mW and derate 5.26mW/ above +70; (5): storage temperature is from -65 to +150; (6): operating temperature is from -40 to +125; (7): lead temperature (soldering, 10s) is 300; (8): junction temperature is +150.
