ADC3582IRSBT

Analog To Digital Converters (ADC) Overview

The ADC3582IRSBT is an 18-bit, 25 MSPS high-speed analog-to-digital converter from Texas Instruments. It operates with a nominal supply voltage of 1.8 V and supports an industrial temperature range from -40°C to +105°C. The device features a noise spectral density of -155.9 dBFS/Hz and delivers a typical signal-to-noise ratio (SNR) of 84.5 dBFS at a 1 MHz input frequency. Power consumption scales with the sampling rate, reaching approximately 126 mW at maximum speed. It utilizes a serial LVDS interface for data output and includes an on-chip digital filter capable of decimation by 2, 4, 8, 16, or 32.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'RSBT' against the manufacturer's orderable addendum to confirm package type and reel specifications. Ensure the operating environment remains within the -40°C to +105°C industrial temperature range. Confirm that the system clock duty cycle adheres to the recommended 40% to 60% specification for optimal performance.

Analog To Digital Converters (ADC) Selection Notes

Select this component when 18-bit resolution and 25 MSPS throughput are required. Compare power dissipation against the ADC3581 (10 MSPS) and ADC3583 (65 MSPS) if speed flexibility is needed. Verify that the external reference voltage matches the 1.6 V requirement or utilize the internal reference if system constraints allow.

Analog To Digital Converters (ADC) Part Context

The ADC3582 belongs to the ADC358x family, which shares pin compatibility and architectural features. It serves as the mid-range speed option between the 10 MSPS ADC3581 and the 65 MSPS ADC3583. All variants in the series offer identical 18-bit resolution and similar dynamic performance characteristics.

Analog To Digital Converters (ADC) Replacement Considerations

Pin-compatible alternatives within the same family include the ADC3581 and ADC3583. These parts share the same package and pinout but differ in maximum sampling rates. Verify that the system timing requirements align with the specific speed grade of the replacement part.
