The ADS62P49IRGCR is a high speed, low power 8-bit, monolithic, dual channel, simultaneous sampling analog-to-digital converter (ADC) that operates from an analog input range of 0V to VDD. It contains an 8-bit ADC and a reference voltage source, a low-power, low-noise amplifier, cyclic-redundancy checks (CRCs), and a voltage reference buffer. Designed for low power consumption, this ADC is suitable for applications where power consumption is a critical factor, such as portable medical and industrial equipment.

The ADS62P49IRGCR’s application field is diverse due to its accompanying features and specifications, making it suitable for use in a variety of different applications and environments. It provides simultaneous sampling of two channels, low-voltage operation, and an integrated voltage reference buffer — all at a max sampling rate of 250MSPS. It also offers excellent linearity performance, a differential analog input range of 5 V, and a programmable power-down feature. Additionally, for improved noise immunity, the reference buffer can be powered down independently of the ADC.

The device\'s working principle is based on the traditional sampling-based data conversion approach. It creates a digital representation of an analog input signal by periodically measuring and comparing it to a reference voltage. The output of the device is a digital code that is a function of the analog input voltage and the reference voltage. The analog-to-digital converter is composed of a comparator, a register, a digital counter, and a logic control unit.

To convert an analog signal, the comparator measures the voltage at an input and compares it to an internal reference voltage. The result of the comparison is then stored in a register. A digital counter is then incremented. The logic control unit will perform the necessary computations to produce an output code. The output code is determined by the number of times the analog input voltage was compared to the reference and the value of the reference voltage. Finally, the digital signal corresponding to the analog signal will be read from the register.

The device also includes a low-power analog-to-digital converter and an integrated voltage reference buffer in order to reduce power consumption. The combination of the two technologies minimizes power and cost, allowing the device to be used in power-sensitive applications. Additionally, the device also provides an external clock input in order to achieve higher throughput rates.

In conclusion, the ADS62P49IRGCR is an 8-bit, monolithic, dual channel, simultaneous-sampling analog-to-digital converter suitable for a variety of different applications. Its key features include low-voltage operation, low power consumption, and a programmable power-down feature. Additionally, the device leverages existing technologies such as a comparison, register, digital counter, and logic control unit, as well as an integrated voltage reference buffer, to deliver efficient data conversion.
