LTC1417CGN#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1417CGN#TRPBF 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. Key specifications include a maximum integral nonlinearity of -1.25LSB, differential nonlinearity of -1LSB with no missing codes over temperature, and an 81dB signal-to-noise plus distortion ratio at Nyquist frequencies.

Analog To Digital Converters (ADC) Feature Summary

• Low power consumption: 20mW typical at 400ksps
• Internal 2.5V reference generating 4.096V output range
• Serial data interface with 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 #TRPBF suffix indicates a tape and reel packaging format for automated assembly. Confirm the 'C' grade designation corresponds to the commercial operating temperature range of 0°C to 70°C as specified in the datasheet. Ensure compatibility with standard 16-pin SSOP footprint requirements during PCB layout.

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 input range to 0V–4.096V (unipolar) or ±2.048V (bipolar). Consider external references if higher voltage ranges or tighter stability than the internal 10ppm/°C tempco are needed.

Analog To Digital Converters (ADC) Part Context

The LTC1417 belongs to Analog Devices' family of low-power successive approximation register (SAR) ADCs. It is functionally similar to the LTC1416 and LTC1418 but offers specific trade-offs in pin count and interface options. The CGN variant specifically denotes the commercial temperature grade housed in the narrow SSOP package.

Analog To Digital Converters (ADC) Replacement Considerations

Publicly confirmed substitute part numbers are not provided in the source documentation. Designers should consult manufacturer cross-reference tools for potential alternatives based on specific performance constraints.
