ADS8318IBDGSR

Analog To Digital Converters (ADC) Overview

The ADS8318IBDGSR is a 16-bit Successive Approximation Register (SAR) analog-to-digital converter manufactured by Texas Instruments. It features a single-ended input configuration and supports sampling rates up to 500 kSPS. The device operates with an analog supply voltage range of 4.5 V to 5.5 V and a digital supply voltage range of 2.375 V to 5.5 V. Key performance metrics include a Signal-to-Noise Ratio (SNR) of 93.9 dB, Differential Nonlinearity (DNL) of ±1 LSB, and Integral Nonlinearity (INL) of ±1.5 LSB. Power consumption is rated at 18 mW. It utilizes a 3-Wire or SPI serial interface and is housed in a VSON-10 package.

• Miniature VSON-10 package design for space-constrained applications

Analog To Digital Converters (ADC) Applications

• Portable medical instrumentation
• Industrial process control systems
• Battery-powered measurement devices

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'DGSR' indicates the tape-and-reel packaging format when ordering. Confirm that the required operating temperature range aligns with the commercial grade specifications. Ensure the host microcontroller supports the 3-wire or standard SPI communication protocol required for data acquisition. Check for moisture sensitivity level requirements during storage and handling procedures.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 16-bit resolution and 500 kSPS throughput are required for single-ended signals. Compare against the ADS8318 variants if differential input capability is needed instead. Evaluate power budget constraints as the device consumes 18 mW during active conversion cycles. Consider the VSON-10 footprint compatibility with existing PCB layouts.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS831x family of precision SAR ADCs from Texas Instruments. It shares architectural similarities with the ADS8316 and ADS8319 but differs in specific pinout configurations and input types. The family is designed for low-power, medium-speed applications requiring high accuracy without the complexity of delta-sigma architectures.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS8318IBDGS is the non-reel counterpart offering identical electrical characteristics in a cut-tape format. For differential input requirements, the ADS8318IBDR may be considered if the package type matches the design constraints.
