Overview
The LTC2305IMS#TRPBF is a 2-channel, 12-bit successive approximation analog-to-digital converter (ADC) produced by Analog Devices Inc. This device is part of the LTC2305 series, known for its low noise, low power consumption, and compact design. The LTC2305 operates from a single 5V supply, drawing only 300μA at a throughput rate of 1ksps, and enters a nap mode when not converting to reduce power dissipation. It features an internal 2.5V reference and a fully differential sample-and-hold circuit to minimize common mode noise. The device is particularly suited for battery-operated and portable applications due to its low power consumption and small size.
