ADS7862Y/2K

Analog To Digital Converters (ADC) Overview

The ADS7862Y/2K is a dual-channel, 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It features simultaneous sampling capabilities with a maximum sampling rate of 500 kS/s per channel. The device integrates an internal reference and supports differential inputs via a parallel interface. It operates on a single 4.75 V to 5.25 V supply for both analog and digital domains. Key performance metrics include a signal-to-noise ratio of 71 dB, differential nonlinearity of ±0.75 LSB, and integral nonlinearity of ±2 LSB. Power consumption is rated at 25 mW, with operation supported across a temperature range of -40°C to +85°C in a 32-pin TQFP package.

Analog To Digital Converters (ADC) Feature Summary

• Dual-channel architecture enabling simultaneous sampling of two independent input signals without interleaving errors.
• Integrated internal voltage reference reduces external component count and simplifies board layout.
• High-speed 500 kS/s sampling rate with 12-bit resolution suitable for precision data acquisition applications.
• Parallel digital interface allows direct connection to microprocessors or DSPs for high-throughput data transfer.

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring multi-channel sensor monitoring
• Medical instrumentation such as portable diagnostic devices
• Data acquisition modules for test and measurement equipment

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix '2K' indicates reel packaging when ordering. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure ESD handling protocols are followed during assembly due to moisture sensitivity classification. Cross-reference the datasheet revision date to ensure compatibility with current design specifications.

Analog To Digital Converters (ADC) Selection Notes

Select this component when simultaneous sampling of two channels is required rather than sequential multiplexing. The integrated reference makes it suitable for cost-sensitive designs where external reference accuracy is manageable. Consider the parallel interface requirements against available processor GPIO resources. Evaluate power constraints given the 25 mW consumption at full speed.

Analog To Digital Converters (ADC) Part Context

The ADS7862 belongs to the ADS786x family of high-speed, low-power ADCs from Texas Instruments. It shares architectural similarities with the ADS7863 and ADS7864 but offers fewer channels. The YB variant denotes the specific package type, while the /2K suffix typically specifies tape and reel packaging for automated assembly processes within the broader product line.
