AD9280ARSRL

Analog To Digital Converters (ADC) Overview

The AD9280ARSRL is an 8-bit, 32 MSPS CMOS analog-to-digital converter (ADC) 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), adjustable internal voltage reference, and parallel digital outputs with three-state capability. Key performance metrics 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 guarantees no missing codes over the industrial temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and reel specifications. Ensure compatibility with system voltage requirements and interface logic levels before integration. Cross-reference the component marking with official datasheets to authenticate the source and revision level.

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 pin-compatible AD876-8 if migrating legacy designs. Evaluate the need for the built-in clamp feature if handling AC-coupled video signals. Verify that the parallel output interface aligns with the downstream FPGA or processor capabilities.

Analog To Digital Converters (ADC) Part Context

The AD9280 is part of Analog Devices' high-speed ADC portfolio designed for cost-effective, low-power applications. It serves as a drop-in replacement for the AD876-8, facilitating upgrades to lower voltage supplies. The device is optimized for imaging and communications where moderate resolution and high speed are required.

Analog To Digital Converters (ADC) Replacement Considerations

The AD9280 is pin-compatible with the AD876-8. For higher resolution needs, consider the AD9218 (10-bit) or AD9251 (14-bit). Verify that substitute components maintain the same pipeline latency and interface timing characteristics.
