ADC3243IRGZ25

Analog To Digital Converters (ADC) Overview

The ADC3243IRGZ25 is a dual-channel, 14-bit analog-to-digital converter (ADC) from Texas Instruments. It supports sampling rates up to 80 MSPS with an analog bandwidth of 540 MHz. The device operates on a single 1.8 V supply and features a serial LVDS interface for high integration density. Key performance metrics include a typical SNR of 72.9 dBFS and SFDR of 93 dBc at fIN = 70 MHz. It includes internal dither, chopper functionality, and multi-chip synchronization support via SYSREF.

Analog To Digital Converters (ADC) Feature Summary

• Dual-channel 14-bit resolution with 80 MSPS maximum sampling rate
• Serial LVDS interface reducing pin count and system complexity
• Ultra-low power consumption: 183 mW total dissipation at 80 MSPS
• Internal clock divider supporting divide-by-1, -2, or -4 ratios

Analog To Digital Converters (ADC) Applications

• Multi-carrier cellular base stations
• Radar and smart antenna arrays
• Software-defined radios (SDRs)
• Communications test equipment

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'RGZ25' against the manufacturer's current orderable addendum to confirm package type and tape/reel specifications. Check for production status updates as component availability may change over time.

Analog To Digital Converters (ADC) Selection Notes

Select the ADC3243 when an 80 MSPS sampling rate is required. For higher speeds, consider the ADC3244 (125 MSPS). For lower speeds, the ADC3241 (25 MSPS) or ADC3242 (50 MSPS) offer reduced power consumption. Ensure the system clock architecture accommodates the internal PLL and divider options.

Analog To Digital Converters (ADC) Part Context

The ADC3243 belongs to the ADC324x family, which also includes the ADC3241, ADC3242, and ADC3244. These devices share pinout compatibility and core architecture but differ in maximum sampling rates ranging from 25 MSPS to 125 MSPS.

Analog To Digital Converters (ADC) Replacement Considerations

The ADC3244 is a direct speed upgrade within the same package. The ADC32J43 is a JESD204B interface alternative with similar resolution but different connectivity requirements.
