description
Dual LT ® 1490 and quad LT1491 op amps, a 2V to 44V drawing, each amplifier has a quiescent current of only 40μA for a total voltage of all single and split supplies to operate. These amplifiers are reverse supply guaranteed; They draw a reverse supply voltage of up to 18V without current. The input range of the LT1490/LT1491 includes two power supplies, two power supplies, and output swing. With most micropower op amps, the LT1490/LT1491 can drive heavy loads with a rail-to-rail output driver of 20 mA. The LT1490/LT1491 are available with 0.22μF and 150 ohm compensation options when driving capacitive loads up to 10,000 pF per unit gain stable. The LT1490/LT1491 has a unique operation that is still higher than the high-impedance input stage at positive supply. Input 44V differential and common mode, even when a 3V supply is operating. Built-in resistance below the fault-protected input with a negative supply voltage of up to 22V. Input V-type below or 22V output above 44V with no phase reversal V-type, independent V+. The LT1490 dual op-amp is available in 8-pin MSOP, SO, and PDIP packages. The quad LT1491 is available in 14-pin SO and PDIP packages. For the new design, it is recommended not to use the LT1490/LT1491 LT1490A/LT1491A. Please refer to the LT1490A/LT1491A data sheet for details.
