ADS800E

Analog To Digital Converters (ADC) Overview

The ADS800E is a monolithic 12-bit, 40MHz sampling Analog-to-Digital Converter (ADC) from Texas Instruments. It utilizes a pipeline architecture with digital error correction to ensure excellent Nyquist differential linearity and guarantee no missing codes. The device operates on a single +5V supply and features an internal reference, wideband track/hold, and three-state outputs. It accepts either differential or single-ended input signals. Key electrical specifications include a typical Signal-to-Noise Ratio (SNR) of 64 dB at 500kHz input frequency, a Spurious-Free Dynamic Range (SFDR) of 72 dBFS, and a power consumption of 390mW. The component is housed in a 28-pin SSOP package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix when purchasing. The 'E' designation indicates the SSOP-28 package variant. Suffixes such as '/1K' denote tape and reel packaging quantities. Confirm availability status as production data may indicate end-of-life or limited stock conditions depending on the distributor. Ensure the required temperature range (-40°C to +85°C) matches the application environment.

Analog To Digital Converters (ADC) Selection Notes

Select the ADS800E for applications requiring high-speed 12-bit conversion with low power constraints. The SSOP-28 package is suitable for surface-mount designs where space is limited compared to the SOIC variant. Consider the 6.5 clock cycle data latency when designing timing interfaces. The device supports both Straight Offset Binary and Two's Complement output coding via the MSBI pin configuration.

Analog To Digital Converters (ADC) Part Context

The ADS800E belongs to the ADS800 family of high-speed ADCs. It shares core specifications with the ADS800U but differs in physical packaging. The ADS800U uses an SOIC-28 package, while the ADS800E utilizes an SSOP-28 package. Both variants offer identical electrical performance characteristics, including sampling rate, resolution, and power consumption, allowing for flexibility in PCB layout and thermal management strategies.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS800U is a direct pin-compatible alternative within the same family, differing only in the SOIC-28 package versus the SSOP-28 package of the ADS800E. No other cross-model replacements are confirmed in the provided documentation.
