ADS58B19IRGZR

Analog To Digital Converters (ADC) Overview

The ADS58B19IRGZR is a single-channel, 11-bit analog-to-digital converter (ADC) from Texas Instruments. It operates at a sampling rate of 250 MSPS with a pipeline architecture. The device accepts single-ended inputs and utilizes 1.8 V for both analog and digital power supplies. Key performance metrics include a signal-to-noise ratio (SNR) of 66 dB, an effective number of bits (ENOB) of 10.83 bits, and a spurious-free dynamic range (SFDR) of 81.7 dB. Differential nonlinearity (DNL) is specified at +/- 2 LSB. The component consumes 310 mW of power and functions within a temperature range of -40°C to +85°C. It is housed in a VQFN-48 package.

• Instrumentation and test equipment
• Medical imaging systems
• Industrial process control

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'RGZR' against the manufacturer's official datasheet to confirm tape-and-reel packaging and industrial temperature grade. Ensure compatibility with existing board layouts regarding the VQFN-48 footprint and thermal requirements. Cross-reference the part number with authorized distributors to validate authenticity and current production status before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an 11-bit resolution and 250 MSPS speed are required for single-channel applications. Consider the single-ended input nature if differential signaling is not mandatory. Evaluate the 310 mW power dissipation against available thermal management solutions. Compare SNR and SFDR specifications against system dynamic range requirements to ensure adequate signal fidelity.

Analog To Digital Converters (ADC) Part Context

The ADS58B19 belongs to the ADS58B18 family of high-performance ADCs. It shares similar architectural features with the ADS58B18 but offers a higher sampling rate of 250 MSPS compared to the 200 MSPS of its sibling. Both devices target similar applications requiring low power and high linearity in a compact VQFN package.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS58B18 is a related device within the same family, offering 200 MSPS instead of 250 MSPS. Verify if the reduced sampling rate meets system requirements as a potential alternative. No other direct pin-compatible substitutes are confirmed in public documentation.
