ADS52J91ZZE

Analog To Digital Converters (ADC) Overview

The ADS52J91ZZE is a low-power, high-performance 16-channel analog-to-digital converter (ADC) from Texas Instruments. It supports configurable resolutions of 10-bit, 12-bit, and 14-bit with maximum conversion rates of 125 MSPS, 100 MSPS, and 65 MSPS respectively. The device accepts differential or single-ended input clocks and operates on 1.2 V and 1.8 V supplies. It features SNR values of 61 dBFS, 69 dBFS, and 73.5 dBFS for the respective modes. Power consumption is 48.6 mW per channel at 125 MSPS. The component utilizes an NFBGA-198 package measuring 9 mm × 15 mm.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix ZZE to confirm the tray packaging format and lead finish specifications. Ensure the moisture sensitivity level rating aligns with your assembly process requirements. Confirm the operating temperature range matches your environmental constraints before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when designing systems requiring simultaneous multi-channel signal digitization with flexible resolution settings. Evaluate the trade-off between sampling speed and power consumption, as higher speeds increase per-channel power draw. Ensure the host system supports the required serialization rates for either the LVDS or JESD204B output interfaces.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS52J91 family of multichannel ADCs designed for high-density data acquisition. It shares architectural similarities with the ADS52J90 but offers increased maximum conversion rates in the lower resolution modes. The device targets applications demanding significant channel counts within a compact footprint.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS52J90 serves as a functional alternative within the same series. Verify compatibility by comparing maximum conversion rates, as the ADS52J90 supports up to 100 MSPS in 10-bit mode compared to the ADS52J91's 125 MSPS limit.

Analog To Digital Converters (ADC) FAQ

How does the device handle input configuration in 8-input mode?

In 8-input mode, two ADCs convert the same input in an interleaved manner, resulting in an effective sampling rate that is twice the ADC conversion rate.

What are the supported JESD204B subclass configurations?

The device supports JESD204B Subclass 0, 1, and 2 while operating in the 16-input and 32-input modes.

Can the device operate with single-ended clock inputs?

Yes, the device supports both differential and single-ended input clocks.
