ADS8344EBG4

Analog To Digital Converters (ADC) Overview

The ADS8344EBG4 is a 16-bit, 8-channel analog-to-digital converter (ADC) manufactured by Texas Instruments. It features a successive approximation register (SAR) architecture with a sampling rate of 100 kS/s. The device supports both differential and single-ended input types via an SPI serial interface. It operates on dual power supplies 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 86 dB, differential nonlinearity (DNL) of ±2 LSB, and integral nonlinearity (INL) of 8 LSB. Power consumption is specified at 3.2 mW, with a maximum power dissipation of 10 mW. 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) Procurement Notes

Verify the specific suffix 'BG4' confirms the QSOP-20 package variant and lead-free compliance status against the manufacturer's current datasheet. Confirm moisture sensitivity level handling requirements during storage and assembly. Ensure the external reference voltage source matches the required precision specifications for the target application. Validate that the SPI timing parameters align with the host microcontroller's capabilities.

Analog To Digital Converters (ADC) Selection Notes

Select this component when eight channels of 16-bit resolution are required at moderate speeds up to 100 kS/s. It is suitable for applications needing low power consumption while maintaining high linearity and noise performance. Consider the QSOP-20 package constraints for PCB layout. Compare with the ADS8345 if slightly different nonlinearity characteristics or alternative packaging options are preferred for the design.

Analog To Digital Converters (ADC) Part Context

The ADS8344 belongs to the ADS834x family of high-resolution, low-power ADCs from Texas Instruments. This series is designed for general-purpose data acquisition tasks where channel count and resolution are critical. The EBG4 designation indicates a specific commercial grade version with enhanced packaging and environmental compliance compared to earlier iterations in the same functional family.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS8345NB is a documented substitute within the same family, offering similar 16-bit resolution and 8-channel capability but with potentially different INL specifications (+/- 6 LSB vs 8 LSB). Verify pinout compatibility and software register settings before substitution.
