The AD7878LPZ-REEL Data Acquisition - Analog to Digital Converters (ADC) device is a bit, low-power, 8-channel high speed Sigma-Delta ADC. It is designed with on-board, programmable gain-amplifier (PGA) and digital filter that can operate up to 6.75Msps while sampling 8 analog inputs. Its single on-chip analog-to-digital converter provides the essential components for small-power applications such as medical, automotive and industrial measurements. Additionally, it integrates dual reference pins and supports 8-bit resolution. This AD7878LPZ-REEL is an ideal solution for low-power applications where low resolution and high speed operation are required.

The AD7878LPZ-REEL ADC has two primary components that work together to convert analog signals into digital signals: a programmable gain-amplifier (PGA) and a Delta-Sigma converter. The PGA is responsible for amplifying the analog signals to levels that are suitable for the Delta Sigma converter. The Delta-Sigma converter then takes those amplified signals and converts them into digital values. This conversion is done through a series of 1-bit steps that are repeated until the desired digital output is achieved. The AD7878LPZ-REEL ADC device uses Delta-Sigma modulation which is a technique that allows high-speed conversion of analog signals into digital signals.

The AD7878LPZ-REEL also supports an External Reference pin, allowing it to use an external voltage reference to set the upper limit of its analog-to-digital conversion range and to improve the accuracy of its results. This pin can also be used to provide a temperature-independent reference voltage.

The AD7878LPZ-REEL provides a wide range of features enabling it to work with a variety of applications. These include a low power consumption (1.2mW/channel at 3.3V), low noise, fast conversion speed (6.75Msps), high resolution (8 bits), programmable gain (1 to 64), an external reference, and a low temperature coefficient. Additionally, it includes an internal temperature sensor and multiple input/output (I/O) options such as an SPI, I2C, and UART for interfacing with external systems.

AD7878LPZ-REEL is well-suited for applications such as ultrasound imaging, medical measurement systems, automotive body electronics, industrial robots, and more. Its integrated temperature sensor and on-board control and configurability make it an ideal solution for applications requiring low power, fast response time, and low noise performance.
