ADC3582IRSBR

Analog To Digital Converters (ADC) Overview

The ADC3582IRSBR is an 18-bit, 25 MSPS high-speed analog-to-digital converter from the Texas Instruments ADC358x family. It operates with a nominal supply voltage of 1.8 V for both analog (AVDD) and digital (IOVDD) sections. The device features a noise spectral density of -155.9 dBFS/Hz and delivers a typical signal-to-noise ratio (SNR) of 84.6 dBFS at a 1.1 MHz input frequency. DC specifications include a typical differential nonlinearity (DNL) of ±0.7 LSB and integral nonlinearity (INL) of ±7 LSB. Power consumption scales with sampling rate, reaching approximately 85 mW to 126 mW at 25 MSPS depending on interface configuration. It utilizes a serial LVDS (SLVDS) interface and is housed in a 40-pin WQFN package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IRSBR against the manufacturer's current orderable addendum to confirm package type, temperature range, and tape/reel specifications. Ensure compatibility with the required 1.8 V supply rails and SLVDS interface timing constraints during system integration.

Analog To Digital Converters (ADC) Selection Notes

Select this component when 18-bit resolution and 25 MSPS throughput are required alongside low power operation. Compare against ADC3581 for lower speed/power needs or ADC3583 for higher bandwidth applications. Consider the internal decimation filters if IF sampling or channelization is necessary within the design.

Analog To Digital Converters (ADC) Part Context

The ADC3582 is part of the ADC358x family, which includes the ADC3581 (10 MSPS) and ADC3583 (65 MSPS). These devices share pinouts and functional blocks, allowing for flexible design upgrades based on bandwidth requirements while maintaining consistent software and hardware interfaces.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible substitutes within the same family include the ADC3581 and ADC3583. Verify that the alternative speed grade meets the system's maximum sampling rate and power budget constraints before substitution.
