LT1469CN8#PBF

LT®1469 is a dual, 16bit accurate operational amplifier. This unique blend of precision and AC performance makes the LT1469 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. The 90MHz gain bandwidth ensures high open-loop gain at frequency for reducing distortion. In noninverting applications such as an ADC buffer, the low distortion and DC accuracy allow full 16bit AC and DC performance. The 22V/µs slew rate of the LT1469 improves large signal performance compared to other precision op-amps in applications such as active filters and instrumentation amplifiers. Applications include precision instrumentation, high accuracy data acquisition systems, 16bit DAC current-to-voltage converter, ADC buffer, low distortion active filters, photodiode amplifiers.
