The HI7188IN is an Analog to Digital Converter (ADC) which allows analog signals to be converted into digital data which can be displayed and used in a digital environment like a computer system. This process, which is used in many areas from digital display systems to audio recording equipment, involves the process of turning a continuous analog signal, such as sound waves or the electrical activity of a sensor, into a series of digital samples.

The HI7188IN is part of the Hi Resolution Series of ADCs by Intersil. It features a 16 bit resolution with a 5V precision reference and a full range of input voltages up to ±10V. It has low power consumption and excellent linearity performance, making it ideal for use in applications requiring very high accuracy.

The device offers two selectable operating ranges. The first range is from 0 to 500mV, with the maximum sampling rate being 3.92kHz. The second range is from 0 to ±10V, with maximum sampling rate of 490kHz. This provides flexibility for users with different input ranges, allowing for higher accuracy for low-level signals and higher speeds for wide-range inputs.

The HI7188IN uses Auto-Calibration, which allows for faster settling times and higher accuracy for the digital samples produced. This reduces the need for calibration and eliminates drift which can occur over time.

The device is well suited to many different applications, including test and measurement instruments, data logging systems, weigh scales and robotic control.

In order to make use of the HI7188IN, it must be connected to the system it is required to operate within. This is done using an analog voltage input, which can be connected using the Voltage Sense or Network Sense pins on the device. The pins are selected using a configuration pin, allowing the user to select the suitable input depending on the application.

Once the device is connected to the system, the HI7188IN is ready to begin the process of Sampling, Conversion, Serialization and Data Output. This process begins when the Sampling pin is triggered to a high voltage level. This causes the device to begin the analog to digital conversion process and the digital output is provided.

The HI7188IN is an extremely capable ADC, offering excellent performance and ease of use. This makes it a great choice for applications that require a high degree of accuracy and stability, such as digital display systems, robotic control and test and measurement equipment.
