ADS7816U/2K5

Analog To Digital Converters (ADC) Overview

The ADS7816U/2K5 is a 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It features a high-speed sampling rate of 200 kS/s and operates on a single 4.5 V to 5.25 V supply, consuming only 1.9 mW of power. The device supports both differential and single-ended input configurations via a 3-wire serial interface compatible with standard SPI. Packaged in an SOIC-8 format, it offers a signal-to-noise and distortion ratio (SINAD) of 72 dB, with differential nonlinearity (DNL) of +/- 1 LSB and integral nonlinearity (INL) of +/- 2 LSB. It functions within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Micro-power consumption enabled by SAR architecture for battery-operated applications
• High-speed 200 kS/s sampling rate with low latency conversion
• Flexible input support for differential or single-ended signals
• Standard 3-wire serial interface for simple microcontroller integration

Analog To Digital Converters (ADC) Applications

• Portable instrumentation requiring low power and moderate speed
• Industrial process control systems
• Data acquisition modules
• Medical equipment

Analog To Digital Converters (ADC) Procurement Notes

Verify the suffix /2K5 indicates reel packaging containing 2500 units. Confirm RoHS compliance status through official datasheets. Ensure the SOIC-8 package matches PCB footprint requirements. Check humidity sensitivity levels for proper storage and reflow soldering profiles.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a balance of 12-bit resolution and 200 kS/s speed is required under a single 5V supply. Compare against ADS7816 variants if different packages like VSSOP are needed. Consider external reference requirements as the device lacks an internal voltage reference.

Analog To Digital Converters (ADC) Part Context

Part of the ADS7816 family of high-speed, micro-power ADCs from Texas Instruments. Shares architectural similarities with ADS7822 and ADS7817 series devices but differs in specific pinouts, input types, and packaging options.

Analog To Digital Converters (ADC) Replacement Considerations

ADS7816EB/250: Different package (VSSOP-8). ADS7816U: Same function, different tape/reel quantity. ADS7822U: Lower power but pseudo-differential input.
