AD7689BCPZ 16 Bit Analog to Digital Converter 8 Input 1 SAR 20-LFCSP
The AD7689BCPZ is a high-performance, 16-bit, successive approximation register (SAR) analog-to-digital converter (ADC) designed for precision data acquisition systems. It features a low-power architecture, making it ideal for battery-powered and portable applications. The device operates with a single power supply ranging from 2.3V to 5.5V, providing flexibility in various system designs. With a throughput rate of up to 500 kSPS, the AD7689BCPZ delivers high-speed, accurate conversions while maintaining excellent linearity and low noise performance. Its integrated reference buffer ensures stable operation, reducing the need for external components.
The AD7689BCPZ incorporates a versatile serial interface (SPI/QSPI/MICROWIRE/DSP-compatible) for easy integration with microcontrollers and digital signal processors. The device supports both unipolar and bipolar input ranges, enhancing its adaptability in diverse measurement scenarios. It also includes a power-down mode to minimize energy consumption during idle periods. The compact 20-lead LFCSP (Lead Frame Chip Scale Package) ensures space-efficient PCB layouts, making it suitable for high-density applications.
