LT1468-2 - 200MHz, 30V/μs 16-Bit Accurate AV ≥ 2 Op Amp

The LT1468-2 is a precision high speed operational amplifier with 16-bit accuracy, decompensated to be stable in a gain of 2 or greater. The combination of precision and AC performance makes the LT1468-2 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 200MHz 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 high slew rate of the LT1468-2 improves large-signal performance in applications such as active filters and instrumentation amplifiers compared to other precision op amps. The LT1468-2 is specified on power supply voltages of ±5V and ±15V and from –40°C to 85°C. For a unity-gain stable op amp with same DC performance, see the LT1468 datasheet.
