ADS8319IBDGSR

Analog To Digital Converters (ADC) Overview

The ADS8319IBDGSR is a precision, single-channel analog-to-digital converter (ADC) manufactured by Texas Instruments. It utilizes a successive approximation register (SAR) architecture to achieve 16-bit resolution with a maximum sampling rate of 500 kSPS. The device operates on a single 5V analog supply and supports digital logic interfaces ranging from 2.375V to 5.5V. It features an SPI-compatible serial interface and is housed in a 10-pin MSOP package. Key performance metrics include a signal-to-noise ratio of 93.9 dB, differential nonlinearity of ±1 LSB, and integral nonlinearity of ±1.5 LSB. The component functions within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'DGSR' corresponds to the tape-and-reel packaging variant when sourcing components. Confirm that the operating voltage requirements align with the target system's power rails. Ensure ESD protection protocols are followed during handling due to the sensitivity of the CMOS input structures. Cross-reference the manufacturer's latest datasheet revision to confirm pinout compatibility and any updates to electrical characteristics before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a balance of moderate speed and high resolution is required for single-ended or pseudo-differential inputs. Consider the external reference requirement if internal reference options are not available in alternative parts. Evaluate the power budget against the 18 mW typical dissipation at full throughput. Verify that the SPI timing parameters meet the host microcontroller's clock speed limitations.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS8319 family of micro-power SAR ADCs from Texas Instruments. The family includes variants with different packaging options such as VSON and standard MSOP. These devices are positioned for applications demanding precision in compact designs. The IB grade indicates specific performance thresholds regarding linearity and noise compared to other industrial grades within the same series.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-to-pin replacements may include other 16-bit SAR ADCs from the same manufacturer with similar interface protocols. Verify compatibility with existing PCB footprints when substituting between MSOP and VSON packages. Check if alternative parts offer integrated references to simplify design if external components were previously used.
