LTC1740IG#PBF

Analog To Digital Converters (ADC) Overview

The LTC1740IG#PBF is a 14-bit, 6Msps sampling analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It operates from a single 5V or dual ±5V supply with a power dissipation of 245mW. The device features true differential inputs with 75dB CMRR and an internal programmable reference supporting ±2.5V or ±1.25V bipolar ranges. Key performance metrics include <1LSB INL, <0.5LSB DNL, 79dB S/(N+D), and 91dB SFDR at 2.5MHz input frequency. It utilizes a parallel digital interface with a separate 3V to 5V output logic supply (OVDD). The component is housed in a 36-lead SSOP package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and RoHS adherence when sourcing. Confirm the 'I' grade designation corresponds to the -40°C to +85°C industrial temperature range required for the application environment. Ensure the 36-lead SSOP package dimensions match the PCB footprint constraints during procurement planning.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring high dynamic range and low distortion at moderate speeds. The flexible input circuit allows adaptation to various signal sources via external references if needed. Consider the 3-cycle pipeline latency when designing the system timing. Ensure the clock source has low jitter to maintain optimal SNR performance given the 80MHz bandwidth.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1740 family of high-speed ADCs. The 'I' suffix denotes the industrial temperature range variant (-40°C to +85°C), while the 'G' suffix typically denotes commercial range. The '#PBF' suffix confirms lead-free packaging. It serves as a complete solution integrating the sample-and-hold, pipelined ADC core, and reference voltage generator.

Analog To Digital Converters (ADC) Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult Analog Devices for current alternatives within the same product family or newer generations that meet the 14-bit, 6Msps specification requirements.
