ADS8383IPFBR

Analog To Digital Converters (ADC) Overview

The ADS8383IPFBR is an 18-bit, 500-kSPS successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It features a unipolar input range and operates with a 5-V analog supply (+VA) and a wide digital supply (+VBD). The device includes an onboard reference buffer and supports 8-, 16-, or 18-bit parallel data bus transfers via BUS18/16 and BYTE control pins. Packaged in a 48-lead TQFP, it is characterized for operation from −40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• 18-bit resolution with no missing codes ensured over the industrial temperature range
• 500-kHz throughput rate with zero latency architecture
• Onboard reference buffer supporting external voltage references
• Flexible parallel interface supporting 8-, 16-, and 18-bit data bus configurations

Analog To Digital Converters (ADC) Applications

• Medical instruments
• Optical networking systems
• Transducer interfaces
• High accuracy data acquisition systems
• Magnetometers

Analog To Digital Converters (ADC) Procurement Notes

Verify that the ordering suffix 'BR' corresponds to the tape and reel packaging format containing 1000 units per reel. Confirm the 'I' designation indicates the industrial temperature grade of −40°C to +85°C. Ensure the specific lot date code aligns with project requirements as manufacturing schedules may vary.

Analog To Digital Converters (ADC) Selection Notes

Select this component when high-resolution 18-bit conversion at 500 kSPS is required. The ADS8383IB variant offers tighter linearity specifications compared to the ADS8383I. Ensure the system design accommodates the separate analog (+VA) and digital (+VBD) power supplies and provides the necessary 2.048-V bias voltage for internal circuitry.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS838x family of high-speed SAR ADCs. It shares architectural similarities with other devices in the series but is distinguished by its specific 18-bit resolution and flexible parallel bus interface options. The IPFBR designation identifies the industrial temperature range version in a 48-pin TQFP package supplied in a tape and reel.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS8383IB serves as a higher-performance alternative within the same package offering improved integral and differential linearity specifications. Other members of the ADS838x family may be considered if different resolution or interface requirements are needed.
