LTC2181CUP#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC2181CUP#TRPBF is a dual-channel, simultaneous sampling 16-bit analog-to-digital converter (ADC) operating at a maximum sampling rate of 40Msps. It features ultralow jitter of 0.07ps RMS and delivers 77dB SNR with 90dB SFDR. The device operates on a single 1.8V supply with total power dissipation of 115mW. It supports selectable input ranges from 1VP-P to 2VP-P and offers full-rate CMOS, DDR CMOS, or DDR LVDS digital outputs. Integrated features include an optional data output randomizer, clock duty cycle stabilizer, shutdown/nap modes, and an SPI configuration port.

Analog To Digital Converters (ADC) Procurement Notes

Verify the 'C' suffix indicates a commercial temperature range of 0°C to 70°C. Confirm the '#TRPBF' suffix specifies tape and reel packaging. Ensure the component is sourced from authorized distributors to guarantee authenticity and traceability.

Analog To Digital Converters (ADC) Selection Notes

Select the LTC2181CUP#TRPBF when a 40Msps sampling rate is required. Choose this part over the LTC2182 if lower power consumption is prioritized over higher speed. Verify that the system requires dual-channel simultaneous sampling and compatible digital interface levels.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC218x family, which includes the LTC2182 (65Msps) and LTC2180 (25Msps). All variants share identical pinouts and architectural features but differ in maximum sampling frequency and associated power dissipation characteristics.

Analog To Digital Converters (ADC) Replacement Considerations

The LTC2182CUP#TRPBF serves as a higher-speed alternative within the same package. The LTC2180CUP#TRPBF is a lower-power option. Direct substitution requires verifying that the specific sampling rate requirements align with the replacement device's capabilities.
