Product Details

The LT1469 is a dual, precision high speed operational amplifier with 16-bit accuracy and 900ns settling to 150μV for 10V steps. 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 16-bit 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.

The LT1469 is available in a space saving 4mm × 4mm leadless package, as well as in small outline and DIP packages. A single version, the LT1468, is also available.
