Advantages of ROHM's D/A converters for electronic adjustment

With the proliferation of digital consumer devices comes increasingly sophisticated analog blocks requiring minute adjustments. Conventional manual adjustment methods using semi-fixed volume adjustments where the adjustments are made at the factory before shipment are inherently difficult to maintain and are susceptible to oscillation, requiring special countermeasures. ROHM's D/A converter LSIs. With the Semi-fixed Volume Method, With ROHM's D/A Converter

1.

Unlike manual adjustment methods, control via microcontroller is possible, enabling multiple adjustments to be performed.

2.

The voltage can be easily changed by varying the microcontroller settings.

3.

Simply connect the D/A converter on the substrate for greater design flexibility.

4.

Eliminates oscillation countermeasures that can adversely affect voltage settings.

5.

No deterioration due to aging or poor contact results in greater reliability.

ROHM D/A Converter LSIs for Electronic Adjustment.

  1. Conventional D/A converter output requires a specific amount of time in order to stabilize voltage due to the analog block. ROHM's D/C converters for electronic adjustment cuts the time to 1/3 and 1/15 the normal period with the 8bit and 10bit models, respectively, significantly decreasing the initial settings time.
  2. All models support a 10MHz clock frequency. Enables common use of serial interface for high speed data transmission with other high speed operation devices.
  3. All models support a 10MHz clock frequency. Enables common use of serial interface for high speed data transmission with other high speed operation devices.
  4. High ESD resistance and no vibration-less system prevent contact failures and deterioration due to wear and tear, resulting in greater precision and higher reliability.
