DESCRIPTION
The LT®1468 is a precision high speed operational amplifier with 16-bit accuracy and 900ns settling to 150μV for 10V signals. This unique blend of precision and AC performance makes the LT1468 the optimum choice for high accuracy applications such as DAC current-to-voltage conversion and ADC buffers. The initial accuracy and drift characteristics of the input offset voltage and inverting input bias current are tailored for inverting applications.
