Analog Devices Inc. LT1468 & LT1468-2 16-Bit Operational Amplifiers

Analog Devices Inc. LT1468 and LT1468-2 16-Bit Operational Amplifiers are precision high-speed Op Amps with 16-bit accuracy and 800ns to 900ns settling time (150μV, 10V step). This unique blend of precision and AC performance makes the T1468 and LT1468-2 ideal 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 LT1468 features a 90MHz gain bandwidth and the LT1468-2 features a 200MHz gain bandwidth.  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 and LT1468-2 improves large-signal performance in applications such as active filters and instrumentation amplifiers compared to other precision Op Amps.

The Analog Devices Inc. LT1468 Op Amp is offered in DFN-8, PDIP-8, and SOIC-8 packages. The LT1468-8 is available in DFN-8 and SOIC-8 packages.
