HI5746KCA

Analog To Digital Converters (ADC) Overview

The HI5746KCA is a high-speed, monolithic analog multiplexer manufactured by Harris Corporation. It features a single-pole double-throw (SPDT) architecture with complementary outputs, designed for applications requiring low distortion and fast switching. The device operates on a single supply voltage ranging from +4V to +30V or dual supplies of ±2V to ±15V. Key electrical parameters include an on-resistance (Ron) of typically 10 ohms, an on-resistance matching (ΔRon) of 0.1 ohm, and a channel-to-channel isolation of 80dB at 1kHz. The switch supports a bandwidth of 100MHz and a settling time of 1μs, ensuring precise signal routing in data acquisition systems.
