PRODUCTION DATA.
The output of the digital compensation is clamped. The low and high clamp values are programmable using the LOW_CLAMP and HIGH_CLAMP registers in the EEPROM. In addition, the user can use the NORMAL_LOW and NORMAL_HIGH registers in the EEPROM to configure the normal operating output. Figure 25 shows an example of the clamping feature for a 0-V to 5-V output operational mode. In a similar way, the output of the compensation can be configured when the 4-mA to 20-mA operational mode is used. In such case, however, the LOW_CLAMP value must be larger than the maximum current necessary for normal operation of the device.
