The AD7880BN is a precision 12-bit SAR (Successive Approximation Register) Analog-to-Digital Converter (ADC) integrated circuit (IC) component manufactured by Analog Devices Inc. It is designed to offer high accuracy and fast conversion speeds for various analog-to-digital conversion applications. Here is a brief overview of the key features of the AD7880BN:
1. Resolution: The AD7880BN provides a resolution of 12 bits, allowing it to convert analog signals into digital values ranging from 0 to 4095.
2. Sample Rate: The IC offers a fast conversion rate of up to 550 kilosamples per second (ksps), enabling real-time data acquisition from the analog input.
3. Input Range: The AD7880BN supports a single-ended input range of 0V to VREF, where VREF is selected by an external reference voltage. It provides a flexible input range, accommodating various signal levels.
4. Low Noise: The ADC features a low noise architecture, allowing for accurate conversions even in noisy environments. This ensures reliable and precise analog-to-digital conversion.
5. On-Chip Track-and-Hold: The IC incorporates an on-chip track-and-hold circuit that holds the input signal constant during the conversion process. This feature minimizes sample distortion and improves accuracy.
6. SPI Interface: The AD7880BN utilizes a Serial Peripheral Interface (SPI) for easy communication with microcontrollers or other digital devices
