The AD7828CQ is an integrated circuit (IC) component that is designed for precise data acquisition applications. It is a 8-channel, 8-bit analog-to-digital converter (ADC) with analog multiplexer and on-chip track-and-hold circuitry. Here are the key features of the AD7828CQ:
1. Conversion Channels: The AD7828CQ has 8 input channels, allowing users to measure and convert analog signals from up to 8 different sources simultaneously. This makes it suitable for applications that require monitoring multiple input signals.
2. Resolution: It offers an 8-bit resolution, meaning it can convert an analog input signal into a digital output with 256 possible discrete values. Though it is not the highest resolution available, it is often sufficient for many general purpose applications.
3. Conversion Speed: The AD7828CQ can perform conversions at a speed of up to 133 kilosamples per second (ksps). This fast conversion rate is beneficial for time-sensitive applications that require real-time measurements.
4. Multiplexing Capability: The IC features an analog multiplexer that enables the user to choose between multiple input channels for conversion. This allows for efficient and flexible acquisition of data from different sources using a single IC.
5. Track-and-Hold Circuit: The on-chip track-and-hold circuitry ensures accurate and precise conversions by holding the input voltage constant during the conversion process
