ADS826E/1K

Analog To Digital Converters (ADC) Overview

The ADS826E/1K is a 10-bit, 60MHz sampling pipeline Analog-to-Digital Converter (ADC) from Texas Instruments. It operates from a single +5V supply and features a high-bandwidth track-and-hold circuit with an internal reference or external reference option. The device supports both single-ended and differential analog inputs, offering a programmable input range of 1Vp-p or 2Vp-p via the RSEL pin. Key electrical specifications include a Signal-to-Noise Ratio (SNR) of 60dB at 1MHz input frequency and a Spurious-Free Dynamic Range (SFDR) of 74dBFS. Power consumption is 265mW in normal operation, reducing to 20mW in power-down mode. The ADS826E variant specifically supports +3V/+5V logic I/O compatibility.

Analog To Digital Converters (ADC) Procurement Notes

Verify that the ordering suffix '/1K' indicates the Tape and Reel transport media containing 1000 devices per reel. Confirm the 'E' suffix denotes the extended temperature range of -40°C to +85°C. Ensure the package designator is SSOP-28 (DB). Cross-reference the specific revision of the datasheet SBAS070B for any parameter updates prior to final procurement.

Analog To Digital Converters (ADC) Selection Notes

Select the ADS826E over the ADS823E when +3V logic interface capability is required, as the ADS826 accepts a +3V clock input while the ADS823 does not. Both parts share identical analog performance and pinouts. Consider the external reference option if multi-channel gain matching or full-scale range adjustment beyond the internal 1.5V–3.5V window is necessary. Ensure the driving amplifier can handle the common-mode voltage requirements of 2.5V for single-ended configurations.

Analog To Digital Converters (ADC) Part Context

The ADS826E is part of the ADS82x family of high-speed pipelined ADCs. It is pin-compatible with the 10-bit, 40MHz ADS822/ADS825 and the 10-bit, 75MHz ADS828. This family utilizes digital error correction techniques to ensure excellent differential linearity and no missing codes. The ADS826E represents the mid-range speed variant within this specific generation of CMOS ADCs designed for demanding imaging and communications applications.

Analog To Digital Converters (ADC) Replacement Considerations

Public confirmed substitute part numbers are not provided in the source documentation. The ADS823E is electrically similar but lacks +3V logic compatibility. For higher speed requirements, the ADS828 is pin-compatible but operates at 75MHz. No direct cross-model replacement is explicitly validated in the text.
