LTC1740CG#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1740CG#TRPBF 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 typical power dissipation of 245mW. The device features a high dynamic range sample-and-hold circuit and a programmable precision reference. Key electrical specifications include an integral nonlinearity error of less than 1 LSB, differential nonlinearity of less than 0.5 LSB, and no missing codes over the operating temperature range. AC performance metrics include a signal-to-noise plus distortion ratio of 79dB and a spurious-free dynamic range of 91dB at an input frequency of 2.5MHz.

Analog To Digital Converters (ADC) Procurement Notes

Verify that the component suffix #TRPBF indicates tape and reel packaging. Confirm the 'C' grade designation corresponds to the commercial temperature range of 0°C to 70°C. Ensure the order matches the specific 36-lead SSOP package requirements for the target PCB layout.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 14-bit resolution and 6Msps throughput are required with low power constraints. It supports both single 5V and dual ±5V supply configurations. The flexible input circuit allows for differential or single-ended signals up to an 80MHz bandwidth. Verify that the external clock jitter does not degrade the SNR below the specified 79dB threshold.
