LTC1415ISW#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1415ISW#TRPBF is a 12-bit, 1.25Msps sampling analog-to-digital converter (ADC) from Analog Devices Inc., housed in a 28-lead plastic SO wide package. It operates on a single 5V supply with a power dissipation of 55mW and supports an industrial temperature range of –40°C to 85°C. The device features true differential inputs with a 4.096V full-scale range, internal reference, and parallel output interface. Key performance metrics include ±0.35LSB INL, ±0.25LSB DNL, 72dB S/(N+D), and 80dB THD at 100kHz input frequency.

Analog To Digital Converters (ADC) Feature Summary

• Differential analog inputs rejecting common mode noise with 60dB CMRR
• Internal 2.5V reference generating 4.096V full-scale input range
• Nap and Sleep power shutdown modes for low-power system flexibility

Analog To Digital Converters (ADC) Applications

• High-speed data acquisition systems
• Imaging systems requiring low linearity errors
• Digital signal processing applications
• Multiplexed data acquisition systems
• Telecommunications equipment

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix #TRPBF indicates tape and reel packaging when sourcing this component. Confirm the ISW variant corresponds to the industrial temperature grade (-40°C to 85°C) and SOIC-28 package. Ensure compatibility with 5V logic levels or configure OVDD for 3V operation as required by the host system design.

Analog To Digital Converters (ADC) Selection Notes

Select the LTC1415ISW#TRPBF for applications requiring high dynamic range and low distortion at moderate speeds. The internal reference simplifies design but requires bypassing REFCOMP. Consider source impedance effects on acquisition time; use buffering for high-impedance sources to maintain full throughput. Verify that the parallel interface timing meets microprocessor or DSP requirements.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1415 family of precision sampling ADCs. The 'I' suffix denotes the industrial temperature range, while 'SW' specifies the 28-lead SOIC package. The '#TRPBF' suffix indicates tape-and-reel packaging and lead-free compliance. It serves as a high-performance alternative to older parallel ADCs in cost-sensitive, medium-speed data conversion designs.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements within the same package and speed class should be verified against the official datasheet. Cross-model substitution requires checking interface compatibility (parallel vs serial) and voltage level alignment. No public substitute part numbers are confirmed in the provided documentation.
