The AD7890BR-2 is an Integrated Circuit (IC) component manufactured by Analog Devices, Inc. It is a high-speed, low-power, 12-bit analog-to-digital converter (ADC). The AD7890BR-2 is specifically designed for applications that require high performance and accuracy.
Key Features:
1. Resolution: The AD7890BR-2 has a resolution of 12 bits, meaning it can digitize an analog signal into 4096 discrete levels.
2. Conversion Speed: It offers a fast conversion speed of up to 100 kilosamples per second (ksps), making it suitable for applications requiring real-time data acquisition.
3. Input Channels: The AD7890BR-2 features a multiplexed input structure with eight single-ended analog input channels. This allows for easy integration with multiple sensors or data sources.
4. Low Power Consumption: It is designed to operate at low power, consuming only 8 milliwatts (mW) during normal operation. This makes it suitable for battery-powered and portable applications.
5. Serial Interface: The AD7890BR-2 supports a serial interface based on the industry-standard Serial Peripheral Interface (SPI) protocol. This enables easy interfacing with microcontrollers or digital signal processors (DSPs).
6. Reference Voltage: It includes an integrated reference buffer and on-chip reference, eliminating the need for an external reference voltage source
