ADS8344EB/2K5

Analog To Digital Converters (ADC) Overview

The ADS8344EB/2K5 is a Texas Instruments 16-bit, 8-channel analog-to-digital converter (ADC) utilizing successive approximation register (SAR) architecture. It features a serial SPI interface and supports sampling rates up to 100 kS/s. The device 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. It accepts pseudo-differential or single-ended inputs and consumes approximately 3.2 mW of power. The component is housed in a QSOP-20 package.

• Portable instrumentation requiring multi-channel precision analog-to-digital conversion
• Battery-powered data loggers and sensor interfaces

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix EB/2K5 against the manufacturer's current datasheet to confirm packaging details and RoHS compliance status. Ensure the ordering part number matches the required tube quantity and temperature grade. Cross-reference the component marking with official TI identification guides to prevent counterfeit substitution during procurement.

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 designs needing low power consumption under 5 V operation. Consider alternative models if higher sampling rates or internal references are necessary, as this variant requires an external reference voltage source for optimal accuracy.

Analog To Digital Converters (ADC) Part Context

This ADC belongs to the ADS834x family of low-power, 16-bit converters. It shares architectural similarities with the ADS8345 but differs in channel count and input type specifications. The device is often paired with Texas Instruments DSPs like the TMS320LC545 in specialized signal processing applications such as electronic transformers.

Analog To Digital Converters (ADC) Replacement Considerations

ADS8345NB: Offers similar 16-bit resolution and speed but supports differential inputs instead of pseudo-differential. ADS8344EVM: Evaluation module for development, not a direct pin-for-pin replacement. Verify pin compatibility and input configuration requirements before substituting.
