LTC2272CUJ#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC2272CUJ#TRPBF is a 16-bit, 65Msps analog-to-digital converter (ADC) featuring a high-speed serial interface compliant with the JESD204 specification. Designed for digitizing high-frequency signals, it provides a full power bandwidth of 700MHz and an input range selectable between 1.5VP-P and 2.25VP-P via an integrated programmable gain amplifier (PGA). The device operates on a single 3.3V supply with typical power dissipation of 990mW at maximum sampling rates. It incorporates an internal clock duty cycle stabilizer to maintain performance across varying clock inputs.

Analog To Digital Converters (ADC) Procurement Notes

Verify that the component matches the Analog Devices Inc. manufacturer identification and the specific model number LTC2272CUJ#TRPBF. Confirm the package type is a 40-lead 6mm x 6mm plastic QFN. Ensure the temperature grade corresponds to the 'C' suffix, indicating operation from 0°C to 70°C. Check for lead-free finish compliance as indicated by the '#PBF' designation in ordering information.

Analog To Digital Converters (ADC) Selection Notes

Select this model over the LTC2273 when a 65Msps sampling rate is sufficient, as it offers lower power consumption compared to the 80Msps variant. Verify that the application requires a 16-bit resolution and supports the JESD204 serial interface protocol. Ensure the system design accommodates the 3.3V analog supply and the OVDD output supply voltage requirements ranging from 1.2V to 3.3V.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC227x family of high-speed ADCs, which includes the LTC2273 (80Msps) and LTC2274 (105Msps). These devices share pin compatibility and architectural features, allowing for flexible design upgrades based on bandwidth requirements. The CUJ suffix denotes the commercial temperature grade and the specific QFN package configuration.

Analog To Digital Converters (ADC) Replacement Considerations

The LTC2273CUJ#TRPBF is a pin-compatible alternative within the same family, offering an increased sampling rate of 80Msps. Designers should verify if the higher speed meets system needs and adjust power management accordingly, as the LTC2273 consumes more power than the LTC2272.
