ADS5204IPFB

Analog To Digital Converters (ADC) Overview

The ADS5204IPFB is a dual 10-bit, 40MSPS Analog-to-Digital Converter (ADC) from Texas Instruments. It features dual simultaneous sample-and-hold inputs with an analog input bandwidth of 300MHz. The device operates on a single 3.3V supply and includes onboard Programmable Gain Amplifiers (PGAs) adjustable from 0dB to 18dB. Key dynamic performance metrics include a Signal-to-Noise Ratio (SNR) of 60dB at fIN = 10.5MHz and a Spurious-Free Dynamic Range (SFDR) of 73dB under the same conditions. Power dissipation is rated at 275mW during normal operation.

Analog To Digital Converters (ADC) Procurement Notes

Verify the package designation PFB corresponds to the TQFP-48 form factor. Confirm the temperature range specification matches the 'I' suffix for -40°C to +85°C operation. Ensure serial control interface requirements align with system design constraints before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when dual-channel high-speed conversion with integrated gain adjustment is required. The internal reference generator simplifies design if external references are unavailable. Consider the 8-cycle pipeline latency when designing timing-critical digital interfaces. Verify clock frequency compatibility with the 40MHz or 80MHz input options.

Analog To Digital Converters (ADC) Part Context

The ADS5204 belongs to the ADS5204 family of dual ADCs. The IPFB variant specifically denotes the industrial temperature range (-40°C to +85°C) and the TQFP-48 plastic leaded chip carrier package. It utilizes a dual pipeline architecture implemented in a CMOS process to achieve low power dissipation while maintaining 10-bit resolution.
