ADC3244EIRGZT

Analog To Digital Converters (ADC) Overview

The ADC3244EIRGZT is a dual-channel, 14-bit analog-to-digital converter (ADC) manufactured by Texas Instruments. It operates at a maximum sampling rate of 125 MSPS and utilizes a pipeline architecture. The device features differential inputs with a peak-to-peak input range of 2 V and an analog input bandwidth of 540 MHz. It supports both external and internal reference modes. Key performance metrics include a signal-to-noise ratio (SNR) of 73.1 dB, an effective number of bits (ENOB) of 11.8 bits, and a spurious-free dynamic range (SFDR) of 93 dB. Power consumption is typically 232 mW, with supply voltages for both analog and digital sections ranging from 1.7 V to 1.9 V. The component is housed in a 48-VQFN package and supports serial LVDS output interfaces.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'E' indicates the extended temperature rating (-50°C to +105°C) compared to standard industrial variants. Confirm the 'IRGZT' suffix corresponds to the tape-and-reel packaging format and RoHS compliance status. Ensure compatibility with the required 1.8 V supply rails and LVDS load conditions before finalizing orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when dual-channel synchronization and 14-bit resolution are required at 125 MSPS. Consider the 540 MHz analog bandwidth for wideband signal capture. Evaluate the 232 mW power dissipation against thermal management capabilities in the 48-VQFN package. Compare SFDR and SNR specifications against system noise floor requirements to ensure adequate dynamic range.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC324x family of high-performance analog-to-digital converters. It shares architectural similarities with the ADC3244 but differs in temperature rating and packaging options. The device complements other TI data converters by offering integrated channel matching and low jitter performance essential for multi-channel systems.

Analog To Digital Converters (ADC) Replacement Considerations

The ADC3244EIRGZ is a pin-compatible alternative differing primarily in tube packaging instead of reel. Verify that the packaging change does not impact automated assembly processes. No functional differences are indicated between these suffixes regarding electrical performance.
