ADC3543IRSBR

Analog To Digital Converters (ADC) Overview

The ADC3543IRSBR is a single-channel, 14-bit analog-to-digital converter from Texas Instruments with a maximum sampling rate of 65 MSPS. It operates on a single 1.8-V supply and features an ultra-low noise floor of –155 dBFS/Hz. The device supports differential inputs and offers SDR, DDR, or serial CMOS digital interfaces. Power consumption scales from 35 mW at 10 MSPS to 84 mW at 65 MSPS. Key performance metrics include a typical SNR of 79.0 dBFS at 10 MHz input frequency and 78.0 dBFS at 64 MHz. It provides one clock cycle latency in parallel modes and includes an optional on-chip digital filter for decimation.

Analog To Digital Converters (ADC) Procurement Notes

Verify the complete part number against the manufacturer's official documentation to ensure correct package and temperature grade specifications. Confirm that the specific ordering suffix matches the required tape-and-reel quantity and RoHS compliance status. Cross-reference the datasheet revision history to validate current production status and any recent parameter updates before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select the ADC3543IRSBR when a 65 MSPS sampling rate is required alongside strict power constraints. Ensure the system design accommodates the 40-pin WQFN package dimensions. Verify compatibility with the chosen digital interface mode (SDR, DDR, or Serial CMOS) regarding FPGA or processor pin availability. Confirm that the external reference voltage meets the 1.6 V requirement if using the internal buffer.

Analog To Digital Converters (ADC) Part Context

The ADC3543 is part of the ADC354x family, which includes the ADC3541 (10 MSPS), ADC3542 (25 MSPS), and ADC3544 (125 MSPS). These devices share pin-out compatibility and architectural similarities, allowing for design flexibility across different speed requirements while maintaining consistent software and hardware integration patterns within the same product line.

Analog To Digital Converters (ADC) Replacement Considerations

The ADC3542 and ADC3541 are pin-compatible lower-speed alternatives within the same family. For higher speed requirements, the ADC3544 is available but operates at 125 MSPS. Verify that the replacement part meets the specific sampling rate and power dissipation needs of the application without requiring schematic modifications.
