kl3356

Product Overview

The KL3356 analog input terminal permits direct connection of a resistor bridge. An improved input circuit makes the KL3356 significantly more accurate than the KL3351. The ratio between the bridge voltage UD and the supply voltage UREF is determined in the input circuit. In order to achieve good long-term stability, the complete circuit is re-calibrated at least every three minutes. This procedure can be synchronized by the control in order to prevent the calibration leading to a delay in the production process.
