Overview
The LTC1609AISW#PBF is a 16-bit, 200ksps serial sampling analog-to-digital converter (ADC) produced by Analog Devices Inc. This device is designed for high precision and low power consumption, drawing only 65mW (typical) from a single 5V supply. It includes a sample-and-hold circuit, a precision reference, and a switched capacitor successive approximation ADC with a trimmed internal clock. The LTC1609 is easy to use and integrates well with microprocessors and digital signal processors (DSPs) due to its high-speed serial interface.
