ADS8383IPFBRG4

Analog To Digital Converters (ADC) Overview

The ADS8383IPFBRG4 is an 18-bit, 500-kHz successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It features a unipolar input range and includes an onboard reference buffer. The device supports flexible data transfer via an 8-, 16-, or 18-bit parallel interface. Powered by a 5-V analog supply (+VA) and a wide digital supply (+VBD), it dissipates 110 mW at maximum throughput. The component is characterized for operation over the industrial temperature range of −40 °C to 85 °C.

Analog To Digital Converters (ADC) Feature Summary

• 18-Bit Resolution: Ensures no missing codes with ±7 LSB integral linearity error across the full temperature range.
• High-Speed Performance: Achieves a 500-kHz sampling rate with a conversion time of 1.52 µs and low aperture jitter of 15 ps.
• Flexible Parallel Interface: Supports 8-bit, 16-bit, and 18-bit bus transfers using BUS18/16 and BYTE control pins.
• Integrated Reference Buffer: Includes an onboard buffer for the reference input, simplifying external circuitry requirements.

Analog To Digital Converters (ADC) Procurement Notes

Verify that the ordering suffix 'RG4' corresponds to the specific tape-and-reel packaging configuration intended for automated assembly. Confirm that the 'I' grade designation meets the required integral linearity specifications for the application environment. Ensure compatibility with the 48-pin TQFP package dimensions during PCB layout.

Analog To Digital Converters (ADC) Selection Notes

Select this component when high-resolution data acquisition is required at speeds up to 500 kHz. The device requires a separate analog supply (+VA) and digital supply (+VBD); ensure the voltage difference between these supplies remains within specified limits. Verify that the host system can accommodate the parallel data bus width and timing constraints defined in the datasheet.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS838x family of high-speed SAR ADCs from Texas Instruments. It is distinguished by its 18-bit resolution and high throughput capability compared to lower-resolution variants in the same product line. The IPFB variant specifically denotes the industrial temperature grade housed in a 48-lead TQFP package.
