LTC1417CGN#PBF

Analog To Digital Converters (ADC) Overview

The LTC1417CGN#PBF is a low power, 14-bit successive approximation register (SAR) analog-to-digital converter operating at sampling rates up to 400ksps. It features a differential high-impedance analog input and serial data output within a 16-lead narrow SSOP package. The device operates from a single 5V supply for unipolar inputs (0V to 4.096V) or dual supplies including –5V for bipolar inputs (–2.048V). Key electrical specifications include a maximum integral nonlinearity of –1.25LSB, a maximum differential nonlinearity of –1LSB with no missing codes over temperature, and typical power dissipation of 20mW. Dynamic performance includes an 81dB signal-to-(noise + distortion) ratio and –95dB total harmonic distortion at a Nyquist input frequency.

• Spectrum instrumentation

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix GN#PBF corresponds to the 16-lead narrow SSOP package and lead-free compliance. Confirm the 'C' grade designation matches the required 0°C to 70°C operating temperature range against application needs. Ensure the ordering documentation explicitly lists Analog Devices Inc. as the manufacturer to avoid counterfeit components.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a balance of moderate speed (400ksps) and high resolution (14-bit) is required with minimal power budget. The internal clock and reference simplify design compared to parallel interface alternatives. Verify that the serial interface timing meets the microprocessor or DSP clock requirements, specifically the SCLK frequency limits up to 20MHz.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1417 family of low-power SAR ADCs. The CGN#PBF designation specifies the commercial temperature grade (0°C to 70°C), the narrow SSOP package, and Pb-free termination. Other variants in the series include higher speed models like the LTC1418 or lower speed versions, but this specific part number defines the 400ksps serial interface configuration.
