ADS804E/1K

Analog To Digital Converters (ADC) Overview

The ADS804E/1K is a 12-bit analog-to-digital converter manufactured by Texas Instruments. It utilizes a pipeline architecture with a single input channel capable of differential or single-ended configurations. The device operates at a sampling rate of 10 MSPS and features a parallel data interface. It requires 5V supplies for both analog and digital sections. The component is housed in a 28-SSOP package with a width of 5.30mm. It supports an operating temperature range from -40°C to 85°C. The part status is listed as Last Time Buy, indicating limited future availability.

Analog To Digital Converters (ADC) Feature Summary

• Pipeline architecture providing high-speed conversion capabilities
• Supports both differential and single-ended input types
• Integrated sample-and-hold function with 1:1 ratio to ADC

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring medium-speed digitization
• Medical imaging equipment utilizing 12-bit resolution signals
• Test and measurement instrumentation interfaces

Analog To Digital Converters (ADC) Procurement Notes

Verify the Last Time Buy status before finalizing design-in decisions, as long-term supply may be restricted. Confirm that the 28-SSOP package dimensions align with existing PCB footprints. Ensure voltage levels match the required 5V analog and digital supply rails. Check for RoHS3 compliance requirements against current environmental regulations. Validate the parallel interface timing constraints with the host processor.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 12-bit resolution and 10 MSPS speed are sufficient for the application. Consider the ADS805E/1K if a higher sampling rate of 20 MSPS is needed, or the ADS807E/1K for 53 MSPS performance. All variants share similar pinouts and packaging. Evaluate the parallel interface complexity against available microcontroller or FPGA resources. Ensure the 5V supply constraint fits within the system power budget.

Analog To Digital Converters (ADC) Part Context

The ADS804E/1K belongs to the ADS80x family of high-speed, low-power analog-to-digital converters. This series includes variants like the ADS805 and ADS807, which offer increased sampling rates while maintaining the same 12-bit resolution and package style. The 'E' suffix denotes the extended industrial temperature range. The '/1K' suffix indicates tube packaging containing 50 units per tube.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS804E/1K is a direct replacement for the standard ADS804E in tube packaging. For reel-based procurement, verify compatibility with ADS804EG4 if available. Higher-speed alternatives include the ADS805E/1K and ADS807E/1K, which maintain pin compatibility.
