Working Principle

The LTC1411IG#PBF utilizes a two-step sampling and conversion process. In the first step, each differential input is held for a predetermined time (set by the hold time capacitor), then the analog input voltage is held for the duration of the hold time plus the conversion time (set by the conversion time capacitor). During this period the amplifier common-mode voltage is determined.

In the second step the latching comparator holds the level of the amplifier output and a successive approximation process begins. This is controlled by the same control logic used for the input latch and conversion time selection. The most significant bit (MSB) is tested for a positive transition, which indicates the input voltage into the amplifier is greater than the MSB voltage. If the result is true (positive) then the MSB changes state before proceeding to the next bit. This process is repeated until all 14-bits are sampled.

Conclusion

The LTC1411IG#PBF is an excellent option for low-cost, low-power, and high-speed data acquisition applications. With features like high resolution, low leakage, and a simplified two-step sampling and conversion process, it is well suited for battery-powered systems, data acquisition applications, and portable instrumentation.
