AD9283BRSZ-100

Analog To Digital Converters (ADC) Overview

The AD9283BRSZ-100 is an 8-bit monolithic sampling analog-to-digital converter (ADC) operating at a maximum conversion rate of 100 MSPS. It features a single 3.0 V power supply (2.7 V to 3.6 V range) and consumes 90 mW at full speed. The device includes an on-chip track-and-hold circuit and a reference voltage, eliminating the need for external components in many applications. It offers a 475 MHz analog bandwidth and supports TTL/CMOS compatible digital outputs with separate logic supply pins for 2.5 V or 3.3 V interfacing. The component is housed in a 20-lead SSOP package.

Analog To Digital Converters (ADC) Feature Summary

• Integrated on-chip track-and-hold circuit and voltage reference simplify system design by reducing external component count.
• Single 3.0 V supply operation with low power consumption of 90 mW at maximum sampling rates.
• TTL/CMOS compatible digital outputs with independent logic supply pin for flexible voltage level interfacing.
• Power-down mode capability reduces total power dissipation to 4.2 mW when inactive.

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 suffix '-100' corresponds to the 100 MSPS performance grade during procurement. Confirm that the SSOP-20 package matches the target PCB footprint. Ensure the industrial temperature range (-40°C to +85°C) aligns with the operational environment requirements. Cross-reference the datasheet revision C specifications against current inventory documentation.

Analog To Digital Converters (ADC) Selection Notes

Select this model when a high-speed 8-bit resolution is required with minimal external support circuitry. The integrated reference and track-and-hold functions make it suitable for space-constrained designs. Consider the 100 MSPS sampling rate against the Nyquist requirements of the input signal frequency. Evaluate the power budget to ensure the 90 mW consumption fits within the system's thermal constraints.

Analog To Digital Converters (ADC) Part Context

The AD9283 series comprises 8-bit ADCs available in 50, 80, and 100 MSPS grades. The BRSZ-100 variant specifically denotes the highest speed bin within the AD9283 family. It shares the same architectural foundation and pinout as lower-speed variants but is characterized for performance up to 100 million samples per second.

Analog To Digital Converters (ADC) Replacement Considerations

AD9283BRSZ-80: Lower sampling rate version of the same architecture. AD9283BRSZ-50: Lowest sampling rate version within the series. These parts share identical pinouts and functionality but differ in maximum clock frequency specifications.
