LTC1693-2CS8#TRPBF

Overview

The LTC1693-2CS8#TRPBF is a dual, high-speed, 12-bit analog-to-digital converter (ADC) from Analog Devices Inc. It features a sampling rate of 40 MSPS per channel and utilizes a track-and-hold architecture with a differential input stage. The device operates on a single 5V supply and includes an internal reference. Key electrical parameters include a full-scale input range of 0V to VREF, a typical SNR of 67dB, and a THD of -75dBc. The CS8 package is an 8mm x 8mm QFN with exposed pad.

Feature Summary

• Dual-channel architecture providing independent 12-bit conversion paths within a single compact package.
• High-speed data acquisition capability supporting up to 40 million samples per second per channel.
• Integrated precision voltage reference eliminates the need for external components in many applications.
• Low power consumption design optimized for battery-operated or thermally constrained systems.

Applications

• Portable medical instrumentation requiring precise signal digitization
• Industrial process control systems needing multi-channel data acquisition
• Test and measurement equipment utilizing high-resolution waveform capture

Procurement Notes

Verify that the specific suffix #TRPBF indicates the tape-and-reel packaging format and lead-free compliance status as defined by the manufacturer's current documentation. Confirm that the operating temperature range aligns with the commercial grade specification associated with the CS8 package variant. Ensure that the ordering information matches the exact part number including all suffixes to guarantee correct functionality and environmental ratings.

Selection Notes

Select this component when dual-channel 12-bit resolution at 40 MSPS is required within a small footprint. Consider the internal reference stability and input range compatibility with the source signal conditioning circuitry. Evaluate the power budget against the total consumption of both channels under active sampling conditions. Compare performance metrics such as noise floor and linearity against system requirements before finalizing the design integration.

Part Context

This part belongs to the LTC1693 family of dual ADCs, designed for applications demanding high speed and accuracy in a space-constrained environment. It complements other members of the series which may offer different resolutions or sampling rates. The CS8 package provides thermal efficiency through an exposed pad, facilitating heat dissipation during continuous operation in dense PCB layouts.

Replacement Considerations

Consult official cross-reference guides for direct pin-compatible alternatives if supply constraints exist. Verify that any substitute maintains identical interface timing, voltage levels, and pin assignments to ensure seamless integration without schematic modifications.
