LT1028 vs LT1128

The LT1028 and LT1128 are both precision operational amplifiers (op-amps) manufactured by Linear Technology (now part of Analog Devices). While they share some similarities, they also have key differences. Here are the main distinctions between the two:

Gain Stability:
LT1028: The LT1028 is designed to be stable at a gain of -1. This means that it is optimized for applications where the inverting configuration is used, and its stability is guaranteed for this gain setting.
LT1128: The LT1128, on the other hand, is stable at a gain of +1. This makes it suitable for applications where a non-inverting amplifier configuration is used with a gain of one or unity gain.

Gain-Bandwidth Product:
LT1028: The LT1028 has a higher gain-bandwidth product of 75 MHz, which makes it more suitable for high-frequency applications that require a higher bandwidth.
LT1128: The LT1128 has a lower gain-bandwidth product of 20 MHz, which means it is better suited for applications that do not require as much bandwidth.

Precision Parameters:
Both the LT1028 and LT1128 are known for their precision and low noise characteristics. They have low drift (0.1 µV/°C), low offset voltage (10 µV), and a high open-loop voltage gain (30 million). These features make them suitable for applications where accuracy and stability are critical.
