Application Field

The MAX547BCQH-D DAC is perfect for applications that require accuracy, high sampling rate and fast settling time. It is especially suitable for audio signal conditioning applications that involve sound pressure level control or amplification. Additionally, it is well-suited for automotive audio systems since it is protected against short circuits.

Other application fields for the MAX547BCQH-D include telecommunications networks, medical instrumentation, sensor signal conditioning, position controllers, servomotors and process control systems.

Working Principle

The MAX547BCQH-D is a low-power, 8-bit DAC with an extended output range. It has a Unipolar or Bipolar output span that makes the converter suitable for a wide range of applications. The output voltage is determined by an 8-bit digital word. By varying this digital word, the user is able to adjust the desired output voltage. A parallel input port is used to interface the DAC with a microcontroller or other digital system.

The converter is capable of rising and settling its output in less than 8µs, making it suitable for high speed filters and signal conditioning applications. In addition, it has a guaranteed high accuracy of 0.3% over temperature and excellent noise performance. Its low power consumption of only 8 mA and 3.3V operation make it one of the most efficient DAC’s available.

The MAX547BCQH-D is available in both 16-pin TSSOP and SOIC packages, making it easy to integrate into existing designs. It also can be used with a wide range of power supplies and both single-ended and differential analog inputs, making integration into end-systems a snap.
