LTC1417IGN#PBF

Analog To Digital Converters (ADC) Overview

The LTC1417IGN#PBF is a low power, 14-bit, 400ksps sampling analog-to-digital converter (ADC) in a 16-lead narrow SSOP package. It operates from a single 5V or –5V supply, consuming typically 20mW at full throughput. The device features a high-performance differential sample-and-hold circuit, an internal precision reference, and serial digital I/O for microprocessor interfacing. DC specifications include ±1.25LSB INL and ±1LSB DNL with no missing codes over the industrial temperature range (-40°C to +85°C). AC performance achieves 81dB S/(N+D) and -95dB THD at a Nyquist input frequency of 200kHz.

Analog To Digital Converters (ADC) Feature Summary

• 14-bit resolution with 400ksps sampling rate
• Low power consumption: 20mW typical at 400ksps
• Internal 2.5V reference generating 4.096V output
• Serial data output with user-selectable Nap and Sleep shutdown modes

Analog To Digital Converters (ADC) Applications

• High-speed data acquisition systems
• Digital signal processing front-ends
• Isolated data acquisition applications
• Audio and telecom signal processing
• Spectrum instrumentation

Analog To Digital Converters (ADC) Procurement Notes

Verify the suffix IGN#PBF indicates the Industrial temperature grade (-40°C to +85°C), Narrow SSOP package, and Pb-free compliance. Confirm that the #PBF designation ensures lead-free tin plating as per RoHS standards. Cross-reference the specific lot date code if long-term availability is required for production runs.

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 external support circuitry. The internal reference simplifies design but limits the maximum input span to 4.096V unless an external reference is used. Ensure the driving source impedance is low enough to meet the 500ns acquisition time requirement at full throughput.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1417 family of low-power SAR ADCs. The 'I' suffix denotes the industrial temperature range variant, distinct from the 'C' commercial grade. It shares the same pinout and core architecture with the LTC1417CGN#PBF but offers extended thermal operating capabilities suitable for broader environmental conditions.

Analog To Digital Converters (ADC) Replacement Considerations

The LTC1417CGN#PBF serves as a direct functional substitute with identical electrical characteristics, differing only in the guaranteed operating temperature range (Commercial vs. Industrial). No other Analog Devices parts share this exact combination of 14-bit resolution, 400ksps speed, and serial interface in a 16-lead SSOP package.
