LTC1415ISW#PBF

Analog To Digital Converters (ADC) Overview

The LTC1415ISW#PBF is a 12-bit, 1.25Msps sampling analog-to-digital converter (ADC) from Analog Devices Inc., housed in a 28-lead plastic SO wide (SOIC) package. It operates on a single 5V supply with a power dissipation of 55mW and supports industrial temperature ranges from -40°C to +85°C. The device features true differential inputs with a 4.096V full-scale range, an internal 2.5V reference, and a parallel microprocessor-compatible digital 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

• 1.25Msps sample rate with 55mW power consumption on a single 5V supply
• Differential analog inputs providing 60dB common mode rejection
• Internal precision reference with external or internal operation options
• 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
• Multiplexed data acquisition applications
• Telecommunications equipment

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and tube packaging when sourcing. Confirm the ISW variant meets the required -40°C to +85°C industrial operating temperature range. Ensure the 28-lead SO wide package dimensions align with the target PCB footprint constraints.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring high dynamic range and low distortion at moderate speeds. The differential input architecture is suitable for rejecting common-mode noise in noisy environments. Consider the separate OVDD pin if interfacing with 3V logic devices is necessary.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1415 family of 12-bit ADCs. The 'I' designation specifies the industrial temperature grade (-40°C to +85°C), while 'SW' denotes the 28-lead SOIC package. The '#PBF' suffix confirms it is a lead-free product compliant with RoHS standards.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements within the same family include the LTC1415CG (commercial grade, SSOP package) and LTC1415CSW (commercial grade, SOIC package). Verify that the commercial grade temperature range (0°C to +70°C) is acceptable for the application environment.
