Analog to Digital Converters (ADC) are devices used for the acquisition of data. An ADC uses an analog input signal and converts it into a digital output signal. The ADS1110A2IDBVT is an example of an ADC. It is a low-power, high-accuracy, 14-bit, low-noise, sigma-delta ADC.

Application Field

The ADS1110A2IDBVT is most suitable for use in medical, industrial, automotive, and consumer applications. It can be used in a variety of medical monitoring applications, such as pulse oximeters, ECG, EEG, and clinical lab equipment. In industrial applications, the AD converter can be used to monitor process control, machine health monitoring, and digital displays. For automotive applications, ADS1110A2IDBVT can be used in safety systems, engine control, instrumentation and chassis control applications. The converter also finds use in consumer applications such as joystick input, music players, and digital cameras.

Working Principle

The ADS1110A2IDBVT uses a sigma-delta conversion technique. This sigma-delta technique is used to convert the analog signal into a digital signal. The analog input signal is integrated and then compared with the threshold voltage. The output of this comparison is a digital bit. Based on the comparison results, an integrator is gated at the right time so that a new bit is generated. This bit is then stored in the device’s latch.

The conversion rate of the ADS1110A2IDBVT is temperature-independent and is adjustable. The device is also equipped with an on-chip oscillator that is used to provide the sampling clock rate. The ADS1110A2IDBVT also has an integral low-dropout voltage regulator (L-DO) for bias supply applications.

The ADS1110A2IDBVT has a auto-zeroing function which can reduce the input offset errors caused by the amplifier. This auto-zeroing function allows the AD converter to continuously sample the input voltage by first resetting the input to zero and then sampling the input voltage.

The ADS1110A2IDBVT also has a differential nonlinearity (DNL) error of ±1 LSB. This allows for a resolution of better than 14 bits, which is ideal for medical, automotive, and industrial applications.

Conclusion

The ADS1110A2IDBVT analog-to-digital converter is a high-accuracy, low-noise, 14-bit sigma-delta converter. It is most suitable for use in medical, industrial, automotive, and consumer applications. The converter has an integral low-dropout voltage regulator (L-DO) and an auto-zeroing function. It is also equipped with a differential nonlinearity (DNL) error of ±1 LSB.
