The LTC2485 is a low-power, high-precision, 24-bit, zero-latency ∆Σ ADC with integrated Easy Drive technology and I2C interface. It features zero differential input current, no latency digital filtering, automatic temperature compensation, a single-chip oscillator, and six available addresses. It is widely used in industrial process control, measurement instruments, direct temperature measurement, direct sensor digitization, and other fields.
The LTC2485 is a 24‑bit, no‑latency analog‑to‑digital converter with Easy Drive™ technology that enables rail‑to‑rail inputs and zero differential input current. It integrates a temperature sensor, internal oscillator, and a 2‑wire I²C interface, supporting programmable 50 Hz, 60 Hz, or simultaneous line‑frequency rejection and a selectable 2× speed mode.
The document details absolute maximum ratings, package information, electrical characteristics for normal and 2× speed modes, converter and timing specifications, typical performance graphs, and related part numbers. It is intended for designers needing precise sensor digitization, weight‑scale applications, instrumentation, and industrial process control.
