ADS8344EB

Analog To Digital Converters (ADC) Overview

The ADS8344EB is a 16-bit, 8-channel analog-to-digital converter (ADC) manufactured by Texas Instruments. It utilizes a successive approximation register (SAR) architecture and supports sampling rates up to 100 kS/s. The device features an SPI-compatible serial interface and accepts pseudo-differential or single-ended inputs. 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 differential nonlinearity (DNL) of ±2 LSB, integral nonlinearity (INL) of 8 LSB, and a signal-to-noise and distortion ratio (SINAD) of 86 dB. 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) Feature Summary

• Motor control applications involving current and voltage sensing

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 external reference circuits as the device requires an external voltage reference. Check moisture sensitivity levels and storage requirements prior to assembly. Confirm that the QSOP-20 footprint matches the design layout. Validate supply voltage ranges against the target application's power rails.

Analog To Digital Converters (ADC) Selection Notes

Select this component when high resolution and multiple channels are required without the need for internal amplification. Compare DNL and INL specifications against system accuracy requirements. Consider the 100 kS/s sampling rate limit for bandwidth constraints. Evaluate power budget against the 3.2 mW consumption figure. Ensure the host processor supports the required SPI communication protocol.

Analog To Digital Converters (ADC) Part Context

The ADS8344EB belongs to the ADS834x family of 16-bit SAR ADCs from Texas Instruments. This series is designed for general-purpose data acquisition tasks. Related models include the ADS8343 and ADS8345, which offer variations in channel count and input configuration. The EVM development kit is available for evaluation purposes.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS8345NB offers similar 16-bit performance but supports differential inputs instead of pseudo-differential. The ADS8341E provides fewer channels but maintains comparable speed and resolution. Verify pinout compatibility before substituting these alternatives.
