ADS803E

Analog To Digital Converters (ADC) Overview

The ADS803E is a high-speed, high dynamic range, 12-bit pipelined Analog-to-Digital Converter (ADC) manufactured by Texas Instruments. It features a high-bandwidth track-and-hold circuit and supports sampling rates up to 5MHz. The device operates with single 5V analog and digital power supplies and accepts both differential and single-ended input signals. It utilizes a parallel data interface for output transmission. The component is housed in a 28-SSOP package and is rated for an operating temperature range of -40°C to 85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the current lifecycle status before procurement, as the ADS803E has been scheduled for obsolescence by the manufacturer. Confirm that the specific package variant matches design requirements. Ensure compatibility with existing 5V logic levels and parallel interface timing constraints. Review official documentation for any pin-compatible alternatives if long-term supply stability is required.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 12-bit resolution and 5MHz sampling rate are necessary for applications requiring high dynamic range. The pipelined architecture offers efficient throughput for continuous signal processing tasks. Consider the 28-SSOP package size for board space constraints. Verify that the parallel interface fits within the system's data bus architecture without requiring additional serial-to-parallel conversion overhead.

Analog To Digital Converters (ADC) Part Context

The ADS803E belongs to Texas Instruments' family of high-performance analog-to-digital converters designed for demanding signal processing applications. As a 12-bit device, it balances resolution and speed effectively. The E suffix typically denotes a specific package or temperature grade variant within the broader ADS803 product line, ensuring compliance with industrial environmental standards.

Analog To Digital Converters (ADC) Replacement Considerations

No direct public substitute part numbers are confirmed for the ADS803E in available documentation. Due to its scheduled obsolescence, engineers should evaluate newer Texas Instruments ADC families with similar specifications for future designs.
