ADS8345EB

Analog To Digital Converters (ADC) Overview

The ADS8345EB is a high-performance, 16-bit, 8-channel analog-to-digital converter (ADC) manufactured by Texas Instruments. It features a successive approximation register (SAR) architecture with a maximum sampling rate of 100 kS/s. The device operates on a single power supply ranging from 2.7 V to 5.25 V for both analog and digital domains. It supports eight single-ended or four differential input channels and communicates via a standard SPI-compatible serial interface. Key electrical specifications include a typical power consumption of 3.2 mW at full speed, a signal-to-noise and distortion ratio (SINAD) of 85 dB, and integral nonlinearity (INL) of ±8 LSB. The component is housed in a QSOP-20 package and functions within an industrial temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'EB' against the official Texas Instruments datasheet to confirm package type and temperature grade. Ensure compatibility with existing board layouts if replacing older variants like the ADS8345E. Confirm moisture sensitivity levels and storage requirements prior to assembly to prevent damage during soldering processes.

Analog To Digital Converters (ADC) Selection Notes

Select this component when 16-bit resolution and 100 kS/s throughput are required for multi-channel signals. Consider the external reference requirement and the specific input voltage range limits. Evaluate the trade-off between power consumption and sampling speed based on system thermal constraints and battery life expectations.

Analog To Digital Converters (ADC) Part Context

The ADS8345 belongs to the ADS834x family of serial output sampling ADCs. It serves as a direct upgrade path for designs previously utilizing the ADS7844 or ADS8344, offering improved performance metrics while maintaining footprint compatibility. This series is designed for applications demanding high accuracy in compact form factors.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS8345N/1K and ADS8345E are functionally equivalent alternatives within the same family, differing primarily in packaging style such as SSOP-20 versus QSOP-20.
