iC-Haus iC-DL 3-Channel Differential Line Driver
ZZZ-iC-Haus iC-DL 3-Channel Differential Line Driver is a fast line driver with six independent channels and integrated impedance adaptation for 30Ω to 140Ω lines. This driver channel is paired for differential 3-channel operation by a high signal at the DIFF input, providing differential output signals for the three inputs. The iC-DL 3-channel line driver monitors supply voltages VB and VCC, and the chip temperature, switching all output stages to high impedance. The push-pull output stages feature a typical driver power of 200mA from 24V and are short-circuit-proof and current-limited. The iC-DL 3-channel line driver is protected against ESD. Typical applications include line drivers for 24V control engineering, linear scales and encoders, and MR sensor systems.
