ADS54J40IRMPT

Analog To Digital Converters (ADC) Overview

The ADS54J40IRMPT is a dual-channel, high-speed analog-to-digital converter manufactured by Texas Instruments. It features a pipeline architecture with 14-bit resolution and supports sampling rates up to 1 GSPS. The device accepts differential analog inputs and operates with an analog supply voltage of 1.9 V or 3 V, alongside a digital supply of 1.9 V. Key performance metrics include a signal-to-noise ratio (SNR) of 69 dB, an effective number of bits (ENOB) of 10.4 bits, and a spurious-free dynamic range (SFDR) of 86 dB. Power consumption is rated at 2.7 W, with a maximum power dissipation of 2.8 W. It is housed in a VQFN-72 package and functions within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Dual-channel configuration for simultaneous multi-signal acquisition
• Ultra-high speed processing capability at 1 GSPS sampling rate
• Differential input structure for improved noise immunity
• External reference requirement for flexible system design

Analog To Digital Converters (ADC) Applications

• Software-defined radio systems
• Wideband instrumentation equipment
• Test and measurement devices requiring high-speed data conversion

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing components. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure export control requirements are met if applicable to the region of manufacture. Validate that the VQFN-72 package dimensions match the target PCB footprint specifications exactly.

Analog To Digital Converters (ADC) Selection Notes

Select this component when dual-channel operation at 1 GSPS is required with 14-bit resolution. Compare SNR and SFDR specifications against system dynamic range requirements. Ensure the 1.9 V and 3 V supply rails align with available power management solutions. Verify thermal management capabilities for 2.7 W power dissipation in the intended enclosure environment.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS54J40 series, which includes variants such as the ADS54J40IRMP. The 'IRMPT' designation specifies the industrial temperature grade, VQFN-72 package, and tape-and-reel shipping format. It shares core architectural features with other members of the family but differs in packaging and handling characteristics.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS54J40IRMP serves as a tray-packaged alternative within the same functional family. Cross-reference pinouts and electrical parameters to ensure compatibility. Verify that any substitute maintains the 1 GSPS sampling rate and 14-bit resolution requirements.
