ADS2807Y

Analog To Digital Converters (ADC) Overview

The ADS2807Y is a dual-channel, 12-bit pipelined analog-to-digital converter (ADC) manufactured by Burr-Brown. It operates at sampling rates up to 50MSPS with a +5V supply and consumes approximately 720mW. The device features a high-bandwidth differential track-and-hold circuit that minimizes even-order harmonics and provides excellent common-mode noise immunity. Key electrical specifications include a Signal-to-Noise Ratio (SNR) of 66dB at 2Vp-p input and 68dB at 3Vp-p input. Differential Linearity Error (DLE) is typically ±0.6LSB, ensuring no missing codes. The ADC supports flexible full-scale input ranges from 2Vp-p to 3Vp-p via an internal or external reference selection.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix for packaging requirements. The standard ADS2807Y is available in a TQFP-64 power package. Suffixes such as /1K5 indicate tape and reel quantities of 1500 units, while /250 indicates 250 units. Confirm the temperature range specification matches the application environment, as the Y variant covers -40°C to +85°C.

Analog To Digital Converters (ADC) Selection Notes

Select the ADS2807Y when dual-channel high-speed conversion is required. Ensure the driving amplifier can support the capacitive load of the track-and-hold circuit; a series resistor of 20Ω to 50Ω is recommended to isolate the source. Choose between internal or external references based on system tracking needs. Verify logic voltage compatibility, as the device supports +3V/+5V CMOS compatible inputs.

Analog To Digital Converters (ADC) Part Context

The ADS2807 is part of the Burr-Brown family of high-speed data converters. It utilizes a pipelined architecture with digital error correction logic to achieve high linearity. The device integrates two 12-bit ADCs, allowing for simultaneous sampling of two signals. It is designed for applications requiring high dynamic range and low power consumption in a compact surface-mount package.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS2807Y/250 and ADS2807Y/1K5 are pin-compatible variants differing only in packaging quantity. For single-channel applications, the ADS801 or ADS803 may be considered, though they offer lower sampling rates. No direct single-pin-for-pin replacement with identical dual-channel specs is listed in the provided documentation.
