ADS4142IRGZT

Analog To Digital Converters (ADC) Overview

The ADS4142IRGZT is a single-channel, 14-bit analog-to-digital converter (ADC) manufactured by Texas Instruments. It operates at a sampling rate of 125 MSPS and utilizes a pipeline architecture. The device features differential analog inputs and parallel digital outputs. It requires a single 1.8 V supply for both analog and digital sections. Key performance metrics include a signal-to-noise ratio (SNR) of 70.9 dB, an effective number of bits (ENOB) of 11.3 bits, and a spurious-free dynamic range (SFDR) of 86 dB. Power consumption is rated at 265 mW. The component is housed in a 48-pin VQFN package and supports an operating temperature range from -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'RGZT' confirms the tape-and-reel packaging format required for automated surface-mount assembly. Confirm the 'I' designation indicates the industrial temperature grade suitable for the intended environmental conditions. Ensure the ordering quantity aligns with the manufacturer's standard reel size specifications to avoid partial reel handling issues during production.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a balance between high resolution and low power consumption is critical. Compare against the ADS4145 if a higher sampling rate of 160 MSPS is required, or the ADS4122 for lower speed applications. Consider the ADS41B49 if enhanced robustness against input overdrive events is necessary for the specific signal environment.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS41xx family of ultralow-power ADCs from Texas Instruments. It shares architectural similarities with the ADS4145 and ADS4122 but offers distinct performance trade-offs regarding sampling speed and power efficiency within the same pin-compatible or form-factor ecosystem designed for communication equipment.

Analog To Digital Converters (ADC) Replacement Considerations

ADS4145IRGZT: Offers 160 MSPS speed with similar power characteristics. ADS4122IRGZT: Provides 65 MSPS speed with potentially lower power usage. ADS41B49IRGZT: Features improved overload recovery capabilities while maintaining comparable resolution.
