ADS4145IRGZT

Analog To Digital Converters (ADC) Overview

The ADS4145IRGZT is a single-channel, 14-bit analog-to-digital converter manufactured by Texas Instruments. It operates at sampling rates of up to 125 MSPS and utilizes a pipeline architecture. The device accepts differential analog inputs and provides parallel digital outputs. It requires 1.8 V for both analog and digital power supplies. Key performance metrics include a signal-to-noise ratio (SNR) of 72.2 dB, an effective number of bits (ENOB) of 11.7 bits, and a spurious-free dynamic range (SFDR) of 80 dB. Total power consumption is 265 mW. The component functions within a temperature range of -40°C to +85°C and is housed in a 48-pin VQFN package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IRGZT to confirm the reel packaging format and industrial temperature grade. Ensure compatibility with the 48-pin VQFN footprint during PCB layout. Confirm RoHS compliance status through the manufacturer's latest documentation before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this model when a single-channel 14-bit resolution is required at 125 MSPS. Compare against the ADS4149 if a higher 250 MSPS rate is needed. Consider the ADS4125 if 12-bit resolution suffices for lower power requirements. Verify that the parallel interface matches the downstream FPGA or processor capabilities.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADS41xx family of ultralow-power ADCs from Texas Instruments. It shares architectural similarities with the ADS4125 and ADS4149 but offers distinct resolution and speed combinations. The series is designed to minimize power dissipation while maintaining high linearity for precision data acquisition applications.

Analog To Digital Converters (ADC) Replacement Considerations

ADS4149IRGZT: Higher speed (250 MSPS), same resolution and package. ADS4125IRGZT: Lower resolution (12-bit), same speed and package. ADS4145EVM: Evaluation module for development, not a direct pin-for-pin replacement.
