AD9283BRS-RL100

Analog To Digital Converters (ADC) Overview

The AD9283BRS-RL100 is an 8-bit monolithic sampling analog-to-digital converter (ADC) operating at a maximum conversion rate of 100 MSPS. It features a 475 MHz analog bandwidth and consumes 90 mW at full speed. The device utilizes a single 3.0 V supply (2.7 V to 3.6 V) and includes an on-chip track-and-hold circuit with a nominal 1.25 V reference. Digital outputs are TTL/CMOS compatible, supported by a separate VD pin for 2.5 V or 3.3 V logic interfacing. Key dynamic performance metrics include a Signal-to-Noise Ratio (SNR) of 46.5 dB at 100 MSPS with a 41 MHz input frequency.

Analog To Digital Converters (ADC) Feature Summary

• Integrated on-chip track-and-hold circuit and voltage reference eliminates the need for external driver components in many applications.
• Single 3.0 V power supply operation simplifies system design and reduces overall component count.
• Separate digital output power supply pin allows flexible interfacing with both 2.5 V and 3.3 V logic families.
• Power-down mode significantly reduces consumption to 4.2 mW while driving digital outputs to a high impedance state.

Analog To Digital Converters (ADC) Applications

• Battery powered instruments
• Hand-held scopemeters
• Low cost digital oscilloscopes

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific speed grade suffix (-100) corresponds to the required 100 MSPS maximum conversion rate. Confirm the SSOP-20 package type matches the target PCB footprint. Ensure the industrial temperature range specification aligns with the operational environment requirements. Check RoHS compliance status if mandated by local regulations.

Analog To Digital Converters (ADC) Selection Notes

Select this model when a high-speed 8-bit resolution is required alongside low power consumption constraints. The integrated reference and track-and-hold simplify the analog front-end design compared to discrete solutions. Consider the 475 MHz bandwidth for signal frequencies up to approximately 76 MHz at 100 MSPS. Evaluate the parallel interface requirements against available FPGA or microcontroller GPIO resources.

Analog To Digital Converters (ADC) Part Context

The AD9283 series comprises three speed grades: -50, -80, and -100, all sharing identical architectural features and pinouts. The -100 variant represents the highest performance tier within this family, optimized for 100 MSPS applications. All variants utilize the same 20-lead SSOP plastic package and operate under similar electrical conditions.

Analog To Digital Converters (ADC) Replacement Considerations

Direct functional replacements within the same package and pinout configuration are limited within the manufacturer's portfolio due to the proprietary pipeline architecture. Verify compatibility with existing clocking and reference circuits before substituting with other ADC families.
