This design approach also means greater flexibility. Dedicated signal conditioners like the MAX15500 support more signal ranges than their integrated counterpart. In cases where high accuracy control is not required, the DAC and voltage reference can be optimized for cost. While only one voltage reference was designed into this reference design, the MAX5135GUE+ is a 12-bit drop-in replacement for the 16-bit DAC used. This reference design also includes a robust and flexible power supply with wide input range and a configurable brown-out alarm for the supply included in the MAX15500 devices.
