ADS7816E/2K5

Analog To Digital Converters (ADC) Overview

The ADS7816E/2K5 is a high-speed, low-power analog-to-digital converter (ADC) manufactured by Texas Instruments. It features a 12-bit resolution and operates with a sampling rate of 200 kS/s. The device supports both differential and single-ended input configurations using a successive approximation register (SAR) architecture. It communicates via a 3-wire serial interface compatible with standard SPI protocols. Power supply requirements range from 4.5 V to 5.25 V for both analog and digital sections. The component is housed in an 8-pin VSSOP package and is rated for operation within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrates a 12-bit SAR ADC core optimized for micropower consumption during active sampling operations.
• Supports flexible signal acquisition through configurable differential or single-ended input modes.
• Utilizes a standard 3-wire serial interface for simplified connectivity with digital control systems.

Analog To Digital Converters (ADC) Applications

• Portable instrumentation requiring low power consumption
• Battery-operated data acquisition systems
• Industrial process control monitoring

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix matches the required packaging format, as the /2K5 designation indicates reel packaging. Confirm RoHS compliance status and moisture sensitivity level prior to assembly planning. Ensure the voltage supply rails strictly adhere to the 4.5 V to 5.25 V specification to maintain performance integrity. Cross-reference the manufacturer's latest datasheet for any potential product change notifications affecting this part number.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a balance between moderate speed and low power is required for 12-bit precision applications. The 200 kS/s sampling rate suits applications that do not demand ultra-high bandwidth but require efficient power management. Consider the VSSOP-8 package constraints for PCB layout density. Verify that the system interface logic levels are compatible with the 3-wire serial communication protocol defined in the electrical characteristics.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS7816 series of micropower sampling ADCs from Texas Instruments. It shares architectural similarities with other devices in the family but is distinguished by its specific 200 kS/s throughput and 12-bit resolution. The E variant denotes commercial temperature grading, while the /2K5 suffix specifies the tape and reel quantity for automated manufacturing processes.
