LT1209CS Description

Short technical summary and product information.

The LT1209CS is a high-speed operational amplifier manufactured by LT. It features a typical gain bandwidth of 45MHz at 100kHz, with a reduced 26MHz bandwidth at a 5V total supply voltage. The device operates with a minimum total supply voltage of 3V, providing an undistorted output swing of 0.8V P-P under this condition. For more realistic operation, ±2.5V supplies are recommended.

Designed for high-speed applications, the LT1209CS boasts a slew rate of 135V/µs when operating with a 5V total supply. It includes slew enhancement circuitry for balanced slewing characteristics. Input considerations include a recommended series resistor for differential input voltages exceeding ±6V and balanced source resistance for DC accuracy.

This operational amplifier is suitable for current-to-voltage conversion, particularly after current output D/A converters. A typical application involves a 5kΩ feedback resistor and a 7pF compensation capacitor to manage DAC output capacitance. The device exhibits a typical phase margin of 50°, which can result in overshoot in the unity-gain small-signal transient response.

The LT1209CS is available in a package designated as LT1209CS. Its wide supply voltage range and high speed make it a versatile component for various electronic designs.
