The LT1995CMS#PBF is a 32MHz high speed gain selectable Amplifier with excellent DC performance. Gains from -7 to 8 with a gain accuracy of 0.2% can be achieved using no external components. The device is particularly well suited for use as a difference amplifier, where the excellent resistor matching results in a typical common mode rejection ratio of 79dB or more. The amplifier is a single gain stage design similar to the LT1363 and features superb slewing and settling characteristics. Input offset of the internal operational amplifier is less than 2.5mV and the slew rate is 1000V/μs. The output can drive a 150R load to ±2.5V on ±5V supplies, making it useful in cable driver applications. The temperature coefficient of the resistors is typically -30ppm/°C. The resistors are extremely linear with voltage, resulting in a gain non-linearity of 10ppm. The LT1995 is fully specified at ±2.5, ±5 and ±15V supplies.
