LTC1740IG#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1740IG#TRPBF is a 14-bit, 6Msps sampling analog-to-digital converter in a 36-lead SSOP package. It operates from a single 5V or dual ±5V supply with 245mW power dissipation. Key electrical parameters include <1LSB typical INL, <0.5LSB typical DNL, and no missing codes. AC performance specifies 79dB S/(N+D) and 91dB SFDR at a 2.5MHz input frequency. The device features true differential inputs with 75dB CMRR, an 80MHz full-power bandwidth sample-and-hold, and a programmable internal reference supporting ±2.5V or ±1.25V ranges.

Analog To Digital Converters (ADC) Procurement Notes

Verify the ordering suffix #TRPBF indicates tape and reel packaging when sourcing this component. Confirm the 'I' grade designation corresponds to the –40°C to 85°C operating temperature range required for your specific application environment. Ensure the 36-lead SSOP footprint matches your PCB design constraints.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring high dynamic range at moderate speeds. The 14-bit resolution and 79dB S/(N+D) make it suitable for precision measurement. Consider the 3-cycle data latency and 100ns conversion time when designing clocking interfaces. The separate OVDD pin allows flexible logic level interfacing with 3V or 5V digital systems.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1740 family of high-speed, high-resolution ADCs. The IG suffix denotes the industrial temperature range variant. The TRPBF suffix specifies the reel packaging format. It is designed as a complete solution integrating the sample-and-hold, pipelined ADC core, and reference circuitry on a single chip.
