ADS8344E/2K5

Analog To Digital Converters (ADC) Overview

The ADS8344E/2K5 is a 16-bit, 8-channel Analog-to-Digital Converter (ADC) utilizing Successive Approximation Register (SAR) architecture. It features an SPI-compatible serial interface and supports sampling rates up to 100 kS/s. The device accepts pseudo-differential or single-ended analog inputs and operates with both analog and digital supply voltages ranging from 2.7 V to 5.25 V. 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 12 LSB. Power consumption is specified at 3.2 mW, with a maximum power dissipation of 10 mW. It requires an external voltage reference and is housed in a QSOP-20 package.

Analog To Digital Converters (ADC) Feature Summary

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and tape-and-reel specifications. Ensure the component meets RoHS compliance requirements for your region. Cross-reference the manufacturer part number with authorized distributor identifiers to prevent counterfeit procurement. Confirm that the external reference voltage source matches the ADC's input requirements for optimal accuracy.

Analog To Digital Converters (ADC) Selection Notes

Select this component when eight simultaneous channels are required within a 16-bit resolution constraint. The ADS8344E/2K5 is suitable for applications where moderate speed (100 kS/s) balances with low power consumption. Designers must account for the need for an external voltage reference, as the device lacks an internal one. Verify that the system's noise floor does not exceed the 86 dB SINAD specification.

Analog To Digital Converters (ADC) Part Context

This part belongs to the Texas Instruments ADS834x family of high-precision, low-power ADCs. It shares architectural similarities with the ADS8345 but differs in channel count and linearity specifications. The 'E' suffix typically denotes an extended temperature range variant, while '/2K5' indicates a specific packaging quantity or reel configuration provided by distributors.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS8345E serves as a functional alternative, offering similar speed and interface but with different channel configurations and INL specifications. Engineers should verify pin compatibility and software register settings when substituting between these family members.
