AD9280ARSZRL

Analog To Digital Converters (ADC) Overview

The AD9280ARSZRL is an 8-bit, 32 MSPS CMOS analog-to-digital converter manufactured by Analog Devices Inc. It utilizes a multistage differential pipeline architecture and operates on a single supply voltage ranging from +2.7 V to +5.5 V. The device features a 300 MHz onboard sample-and-hold amplifier (SHA) and guarantees no missing codes across the industrial temperature range of -40°C to +85°C. Key electrical specifications include a typical power dissipation of 95 mW at 3 V, a signal-to-noise ratio (SNR) of 49 dB, and a differential nonlinearity (DNL) of ±0.2 LSB. It provides parallel CMOS/TTL digital outputs with three-state capability.

Analog To Digital Converters (ADC) Feature Summary

• Includes a built-in clamp function for DC restoration of video or AC-coupled signals
• Features an out-of-range indicator (OTR) to detect overflow conditions
• Supports flexible input configurations including single-ended and differential modes

Analog To Digital Converters (ADC) Applications

• Imaging systems requiring high-speed data acquisition
• Communications systems utilizing IF undersampling up to 135 MHz
• Video signal processing applications involving DC restoration
• Instrumentation equipment operating within industrial temperature ranges

Analog To Digital Converters (ADC) Procurement Notes

Verify that the specific ordering suffix matches the required package type and reel configuration. Confirm that the component meets RoHS compliance standards for your region. Ensure the supplier provides valid traceability documentation. Check for any specific handling requirements related to electrostatic discharge sensitivity during storage and assembly processes.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an 8-bit resolution and 32 MSPS sampling rate are sufficient for the application. Consider the internal reference options if external precision references are not available. Evaluate the power consumption against system thermal constraints, noting the low-power sleep mode availability. Ensure the input signal range aligns with the configurable reference voltage settings.

Analog To Digital Converters (ADC) Part Context

This part belongs to the AD9280 series of high-speed, low-power ADCs from Analog Devices. It is designed as a drop-in replacement for older architectures while offering improved performance in modern low-voltage environments. The SSOP-28 package allows for compact board layouts in space-constrained designs.

Analog To Digital Converters (ADC) Replacement Considerations

The AD9280 is explicitly pin-compatible with the AD876-8. Designers migrating from the AD876-8 can utilize this component directly without PCB layout changes, provided they adjust for the different supply voltage requirements and reference configurations.
