Related Q&A Q1: How does the LTC1098 handle signal sampling? - A1: The LTC1098 uses a multiplexing scheme to select one of the eight input channels. The selected input is then sampled and converted into a digital signal with 12-bit resolution. Q2: What is the power consumption of the LTC1098? - A2: The LTC1098 is designed to operate with low power consumption, typical in battery-operated devices. Specific power consumption can vary based on the sample rate and operating conditions but is generally in the microamp range when in low power mode. Q3: Can the LTC1098 be used in single-ended and differential applications? - A3: The LTC1098 is primarily designed for single-ended analog signals. For differential applications, additional signal conditioning might be required. Q4: What is the maximum sampling rate for the LTC1098? - A4: The LTC1098 can typically sample at a rate of up to several hundred kSPS (kilosamples per second). However, the exact rate depends on the configuration and external clocking used in the application. Q5: How do I interface the LTC1098 with a microcontroller? - A5: The LTC1098 uses a serial output interface; it connects to the microcontroller using SPI or a similar protocol.
