LT1490A Overview
Key Specifications
Mount Type: Through Hole
Pins: 8
Max Voltage (typical range): 44 V
Min Voltage (typical range): 2 V
Key Features
- It is recommended for all new designs
- It is reverse supply protected; it draws virtually no current for reverse supply up to 18V
- The input range of the LT1490A includes both supplies and the output swings to both supplies
- Unlike most micropower op amps, the LT1490A can drive heavy loads; its rail-to-rail output drives 20mA
- The LT1490A is unity-gain stable and drives all capacitive loads up to 10,000pF when optional 0.22µF and 150Ω compensation is used
- The LT1490A has a unique input stage that operates and remains high impedance when above the positive supply
- The inputs take 44V both differential and common mode even when operating on a 3V supply
- Built-in resistors protect the inputs for faults below the negative supply up to 15V
- There is no phase reversal of the output for inputs 15V below V – or 44V above V –, independent of V +
