MAX198BCNI

ADC’s/DACs’, or analogue to digital converters and digital to analogue converters, are extremely useful pieces of modern technology. They are used in all sorts of applications, from notebook PCs to audio systems, as well as specialized applications such as medical and industrial. One particularly important device for special applications is the MAX198BCNI.

The MAX198BCNI is a 10-bit low voltage sigma-delta analog to digital converter, designed for high speed and low power applications, making it the ideal solution for a number of special requirements. The device comes in an 8-pin Micro-small outline (MSOP) package and operates over the supply voltage range of 1.7V to 5.5V. The MAX198BCNI is also specified at 1.8V and is available in a true 3.3V HV version.

MAX198BCNI Application Field

The MAX198BCNI is ideal for applications dictated by low power, low cost and/or small size such as portable batteries, medical and wearable applications. Its low power operation gives the device a wide range of possible applications, ranging from low-power data acquisition to testing and monitoring. The MAX198BCNI also features features a low-noise internal clock frequency, allowing it to be used for high resolution and frequency-selective measurements.

The MAX198BCNI also features an unprecedented small form factor and wide operating temperature range (–40°C to +85°C). This makes the device ideal for battery-powered equipment, remote monitoring, and other high-temperature applications.

MAX198BCNI Working Principle

The MAX198BCNI operates based on a sigma-delta (ΔΣ) modulator principle, which is a type of analogue to digital conversion technique that is well suited to low power applications. The modulator is essentially an oversampling DAC with feedback and a digital filter, and is traditionally used to convert analogue input signals into a digital signal.

The device operates by repeatedly sampling an analogue signal, and converts it into a digital signal with an internal cycling loop. The number of bits in the digital signal is proportional to the number of cycles the loop completes. The device offers 10-bit resolution with a sample speed of up to 200kHz, making it suitable for a wide range of low frequency and high-speed applications.

The MAX198BCNI also offers a programmable output data rate, allowing it to be adjusted to the specific requirements of the application. This flexibility makes the device suitable for use in a number of different applications, such as system testing, communication systems, battery-powered operations, and remote monitoring.

Conclusion

In conclusion, the MAX198BCNI is an efficient and low-power 10-bit ADC/DAC, ideal for a number of applications including system testing, communication systems, battery-powered operations, and remote monitoring. The device offers excellent flexibility with its adjustable output data rate and wide operating temperature range, making it a top choice for a variety of special requirements.
