LTC2233IUK#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC2233IUK#TRPBF is a 10-bit, 80Msps high-speed analog-to-digital converter (ADC) from Analog Devices Inc. It features a single 3.3V supply and low power dissipation of 406mW. The device offers a signal-to-noise ratio (SNR) of 61.3dB and spurious-free dynamic range (SFDR) of 78dB up to 200MHz input frequency. It includes selectable input ranges of ±0.5V or ±1V, an optional clock duty cycle stabilizer, and separate output logic supply (OVDD). The component is housed in a 48-lead 7mm x 7mm QFN package with an exposed ground pad.

• 80Msps sampling rate with 61.3dB SNR at 2V range
• Ultralow jitter of 0.15ps RMS for undersampling applications
• Selectable input ranges: ±0.5V or ±1V via SENSE pin

Analog To Digital Converters (ADC) Applications

• Wireless and wired broadband communication systems
• Cable head-end systems
• Power amplifier linearization
• Communications test equipment

Analog To Digital Converters (ADC) Procurement Notes

Verify the #TRPBF suffix indicates lead-free tape and reel packaging. Confirm the 'I' grade designation corresponds to the -40°C to +85°C operating temperature range. Ensure the 48-pin QFN package dimensions match the PCB footprint requirements.

Analog To Digital Converters (ADC) Selection Notes

Select this model over the LTC2232 if an 80Msps sampling rate is sufficient, as it consumes less power (406mW vs 535mW). Consider the LTC2234 if 10-bit resolution at 135Msps is required. Verify that the external reference voltage matches the selected SENSE pin configuration for the desired input range.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC2232/LTC2233 family of 10-bit ADCs. It is pin-compatible with the LTC2232 (105Msps) and the LTC2234 (135Msps). The IUK variant specifies the industrial temperature range and the specific 48-lead QFN physical package.

Analog To Digital Converters (ADC) FAQ

How is the input range selected?

The input range is selected by connecting the SENSE pin to VCM for ±0.5V or to VDD for ±1V. An external reference can also be applied to set intermediate ranges.

What is the pipeline latency?

The LTC2233 has a pipeline latency of 5 cycles.

Can the device operate with single-ended inputs?

Yes, the analog inputs can be driven single-ended, though differential drive provides optimal AC performance and harmonic distortion characteristics.
