Analog to Digital Converters

ADC0809CCVX/NOPB Description

The ADC0809CCVX/NOPB from Texas Instruments is an 8-bit successive approximation register (SAR) analog-to-digital converter (ADC) designed for precision signal acquisition in embedded systems. Housed in a 28-pin PLCC package, this surface-mount IC features an 8-channel multiplexer, enabling single-ended input measurements across multiple analog sources. With a sampling rate of 10 kSPS, it delivers reliable conversion performance for moderate-speed applications. The device operates on a 4.5V to 6.5V dual supply (analog/digital), ensuring compatibility with standard logic levels. Its external reference architecture allows flexibility in setting the input range, while the 1:1 sample-and-hold (S/H) to ADC ratio ensures accurate signal capture.

ADC0809CCVX/NOPB Features

• 8-Bit Resolution: Provides sufficient accuracy for industrial control and sensor interfacing.
• 8-Channel Multiplexer: Supports single-ended inputs, reducing external component count.
• Parallel Data Interface: Enables straightforward integration with microcontrollers or FPGAs.
• 10 kSPS Sampling Rate: Ideal for mid-speed data acquisition in automation and instrumentation.
• Wide Supply Range (4.5V–6.5V): Compatible with 5V systems and tolerant of minor voltage fluctuations.
• SAR Architecture: Balances speed and power efficiency, suitable for battery-powered devices.
• RoHS3 Compliant & REACH Unaffected: Meets environmental and regulatory standards.
• Tape & Reel Packaging: Optimized for automated assembly in high-volume production.

ADC0809CCVX/NOPB Applications

This ADC excels in scenarios requiring multi-channel analog signal digitization with moderate speed and low complexity. Key applications include:

• Industrial Control Systems: Monitoring sensors (e.g., temperature, pressure) in PLCs.
• Consumer Electronics: Embedded control in appliances or audio equipment.
• Automotive Diagnostics: Reading analog signals from vehicle subsystems.
• Medical Devices: Portable instruments with multi-parameter sensing.
• Legacy System Upgrades: Drop-in replacement for older 8-bit ADCs due to pin compatibility.

Conclusion of ADC0809CCVX/NOPB

The ADC0809CCVX/NOPB offers a cost-effective, reliable solution for 8-bit analog-to-digital conversion, particularly in multi-channel environments. Its simplicity, parallel interface, and robust supply range make it a pragmatic choice for designers modernizing legacy systems or developing new applications with moderate throughput requirements. While newer ADCs may offer higher resolution or speed, this device remains relevant for its ease of use, proven architecture, and Texas Instruments' quality assurance. Note: This product is marked as Last Time Buy, indicating end-of-life status; alternatives like the ADS7886 (12-bit SAR ADC) should be evaluated for future designs.
