ADS8345EB/2K5

Analog To Digital Converters (ADC) Overview

The ADS8345EB/2K5 is a 16-bit, 8-channel serial output sampling analog-to-digital converter (ADC) manufactured by Texas Instruments. It features a successive approximation register (SAR) architecture with a maximum throughput of 100 kS/s. The device supports single-ended or differential input configurations and operates on a single supply voltage ranging from 2.7 V to 5.25 V for both analog and digital domains. Key performance metrics include a Signal-to-Noise and Distortion Ratio (SINAD) of 85 dB, integral nonlinearity (INL) of ±8 LSB, and differential nonlinearity (DNL) of ±2 LSB. It is housed in a QSOP-20 package and functions within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Supports flexible input modes including eight single-ended or four differential channels
• Integrates a low-power shutdown mode to minimize energy consumption during idle periods
• Features a synchronous serial interface compatible with standard SPI protocols

Analog To Digital Converters (ADC) Applications

• Data acquisition systems requiring multi-channel signal monitoring
• Industrial process control instrumentation
• Portable battery-powered measurement devices

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'B' against official documentation to confirm any distinct manufacturing lot or revision differences compared to the standard 'E' variant. Ensure compatibility with the required QSOP-20 packaging format and validate that the operating temperature range meets the target application's environmental specifications before finalizing procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an 8-channel configuration is necessary, as opposed to the 4-channel ADS8344. It is suitable for applications demanding 16-bit resolution at moderate speeds up to 100 kS/s. Consider the external reference requirement if high precision is needed, as the device does not integrate an internal voltage reference.

Analog To Digital Converters (ADC) Part Context

The ADS8345 belongs to the ADS834x family of high-performance ADCs from Texas Instruments. This series includes variants such as the ADS8344 and ADS8341, which offer different channel counts while maintaining similar architectural characteristics. The ADS8345 specifically addresses applications requiring higher channel density than the 4-channel counterparts.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS8344 is a pin-compatible alternative offering 4 channels instead of 8. The ADS8341 provides a 4-channel configuration with potentially different electrical characteristics. Verify pinout and functional compatibility before substituting.
