Data Acquisition - Analog to Digital Converters (ADC)

The MAX1066BCUP+ is a low-power, 8-bit analog-to-digital converter (ADC) with an on-chip voltage reference. The device is offered in an 8-pin plastic DIP package optimized for single-supply operation, making it suitable for battery-operated equipment. It has an 8-bit charge-redistribution successive-approximation type A/D converter, an internal 2.56V voltage reference, and supporting circuitry.

Application Field

The MAX1066BCUP+ is designed for use in systems where low power consumption, small size, and low cost are of primary importance. This ADC is useful for low-speed, slowly varying signals found in applications involving remote control or sensor measurements. Examples of such applications include measuring temperature, voltage, pressure, weight, and audio signals. Its low power consumption also makes it attractive for battery-operated systems.

Working Principle

The MAX1066BCUP+ combines a successively-approximating analog-to-digital converter (ADC) with a low-power Voltage Reference. The ADC\'s converter topology is based on a successive-approximation register (SAR). The 8-bit SAR structure is connected to an input latch, internal reference, and a voltage comparator. It consists of two comparator cycles of 4 bits each.

When the device is powered up, it performs a power-on-reset (POR). After the POR sequence, the device performs a “conversion cycle”. In the conversion cycle, a sample of the input signal is taken on the input latch. The sample is compared against the internal reference voltage. Depending on the result of the comparison, a “hit” or “miss” bit is generated. These hit/miss bits are then sent through the SAR structure. As the SAR structure progresses through its four-bit-long conversion cycle, the bit-stream is updated, thus producing a digital representation of the analog input.

Conclusion

The MAX1066BCUP+ is a low-power, 8-bit successive-approximation type analog-to-digital converter designed for use in a variety of applications. It is suitable for battery-operated equipment because of its low power consumption. Its 8-bit SAR structure, internal voltage reference, and supporting circuitry enable efficient analog-to-digital conversion.
