LTC2288CUP#PBF

Analog To Digital Converters (ADC) Overview

The LTC2288CUP#PBF is a dual-channel, 10-bit analog-to-digital converter (ADC) operating at a sampling rate of 65Msps. It utilizes a pipelined architecture and functions on a single 3V supply (2.7V to 3.4V). Key performance metrics include a signal-to-noise ratio (SNR) of 61.8dB and a spurious-free dynamic range (SFDR) of 85dB. The device features flexible input ranges from 0.5VP-P to 2VP-P, an internal reference, and supports multiplexed or separate digital output buses. It is housed in a 64-lead QFN package.

Analog To Digital Converters (ADC) Feature Summary

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific temperature grade suffix for the required operating range. The 'C' suffix denotes commercial range (0°C to 70°C), while 'I' denotes industrial range (-40°C to 85°C). Confirm that the #PBF designation indicates lead-free compliance before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when dual-channel digitization at 65Msps is required with low power constraints. Compare against the LTC2287 (40Msps) or LTC2286 (25Msps) if lower sampling rates suffice for reduced power dissipation. Ensure the analog input common mode voltage aligns with the 1.5V bias provided by the VCMA/VCMB pins.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC2288/LTC2287/LTC2286 family of low noise 3V ADCs. It is pin-compatible with the LTC2293 (12-bit, 65Msps) and other variants in the series, allowing for design flexibility across different resolution and speed requirements within the same footprint.

Analog To Digital Converters (ADC) Replacement Considerations

The LTC2287CUP#PBF and LTC2286CUP#PBF are pin-compatible alternatives offering lower sampling rates (40Msps and 25Msps respectively) with corresponding reductions in power dissipation.
