ADS8344EG4

Analog To Digital Converters (ADC) Overview

The ADS8344EG4 is a 16-bit, eight-channel successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It features an SPI-compatible serial interface and supports sampling rates up to 100 kSPS. The device accepts pseudo-differential or single-ended inputs and operates on dual 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 of ±2 LSB, and integral nonlinearity of 12 LSB. It is housed in a 20-lead QSOP package and functions within a temperature range of -40°C to +85°C.

• Scientific measurement and analysis devices

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'EG4' against the manufacturer's current datasheet to confirm RoHS compliance status and pinout compatibility. Ensure the ordering part number matches the required package type and temperature grade before procurement. Cross-reference the component marking with official documentation to prevent substitution errors during assembly.

Analog To Digital Converters (ADC) Selection Notes

Select this component when designing systems that require moderate-speed, high-resolution multi-channel sampling. It is suitable for applications where power consumption must be minimized while maintaining 16-bit accuracy. Consider the external reference requirement if system noise budgets are tight, as internal references are not provided in this specific model variant.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADS834x family of low-power, 16-bit ADCs from Texas Instruments. It shares architectural similarities with the ADS8341 and ADS8343 but offers eight channels compared to fewer in other variants. The EG4 designation typically indicates lead-free construction compliant with environmental directives.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS8344E is the standard commercial version of this component. Verify pin-for-pin compatibility and electrical parameter equivalence before substituting. Other family members like the ADS8341 offer fewer channels and may not fit multi-channel requirements directly.
