Overview
The LTC2305IDE#PBF, produced by Analog Devices Inc., is a 2-channel, 12-bit successive approximation analog-to-digital converter (ADC) with an I²C compatible serial interface. This ADC is designed for low noise and low power consumption, making it ideal for battery-operated and portable applications. It operates from a single 5V supply and features an internal 2.5V reference, which reduces PCB board space requirements. The device includes a fully differential sample-and-hold circuit to minimize common mode noise and achieves a fast 1.3μs conversion time using an internal clock.
