ADS54J54IRGC25

Analog To Digital Converters (ADC) Overview

The ADS54J54IRGC25 is a quad-channel, 14-bit analog-to-digital converter (ADC) manufactured by Texas Instruments. It supports sampling rates up to 500 MSPS and utilizes a pipeline architecture. The device features differential analog inputs and offers flexible digital output interfaces, including DDR LVDS and parallel CMOS options. It operates on a single 1.8 V supply for both analog and digital sections. The component is housed in a 64-pin VQFN package with dimensions of 9 x 9 mm. Key performance metrics include a typical SNR of 71.4 dB at Nyquist frequencies.

• Software-defined radio systems
• Instrumentation and test equipment

Analog To Digital Converters (ADC) Part Context

The ADS54J54 belongs to the ADS54J family of high-performance, low-power ADCs from Texas Instruments. This series is engineered for applications requiring multiple channels with high dynamic range and speed. The IRGC25 suffix indicates the industrial temperature range (-40°C to +85°C) and the specific VQFN-64 packaging variant. These devices are designed to replace older multi-chip solutions by integrating multiple converters into a compact form factor.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-to-pin replacements within the same package may be limited due to specific interface requirements. Consider the ADS54J66 or ADS54J69 for higher resolution or different speed grades, though pin compatibility must be verified against the specific datasheet revision. Legacy equivalents like the ADS62P29 offer dual-channel architectures but differ in channel count and interface options.
