ADC3543IRSBT

Analog To Digital Converters (ADC) Overview

The ADC3543IRSBT 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 consumes 84 mW at full speed. The device features an input bandwidth of 900 MHz and achieves a signal-to-noise ratio (SNR) of 79.0 dBFS at 10 MHz input frequency. Key specifications include a noise spectral density of -154.7 dBFS/Hz, integral nonlinearity (INL) of ±0.6 LSB, and differential nonlinearity (DNL) of ±0.1 LSB. It supports SDR, DDR, and serial CMOS interfaces and includes an optional on-chip digital down-converter.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix 'BT' against the manufacturer's official package option addendum to confirm tape-and-reel availability and quantity. Ensure the component meets RoHS compliance requirements for your region. Confirm that the WQFN-40 package thermal characteristics align with your system's heat dissipation capabilities before finalizing procurement.

Analog To Digital Converters (ADC) Selection Notes

Select the ADC3543 when a 65 MSPS sampling rate is required for 14-bit resolution. Compare power consumption against lower-speed variants like the ADC3541 or ADC3542 if system power budgets are tight. Verify that the 900 MHz input bandwidth and 79 dBFS SNR meet the dynamic range requirements of the target application signal frequencies.

Analog To Digital Converters (ADC) Part Context

The ADC3543 belongs to the ADC354x family, which also includes the ADC3541 (10 MSPS), ADC3542 (25 MSPS), and ADC3544 (125 MSPS). These devices share pin compatibility and architectural features, allowing designers to scale performance without changing the PCB layout. The family targets low-power, high-precision applications requiring flexible digital output formats.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements within the same family include the ADC3541, ADC3542, and ADC3544. When substituting, verify that the sampling rate and power consumption of the alternative part match the design constraints. Ensure the digital interface configuration remains compatible with the host processor.
