LTC1279ISW#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1279ISW#TRPBF is a 12-bit, 600ksps sampling analog-to-digital converter manufactured by Analog Devices Inc. It operates from a single +5V or ±5V supply and features an internal synchronized clock, eliminating the need for external timing components. The device includes a precision 2.42V internal reference and offers flexible unipolar (0V to 5V) or bipolar (±2.5V) input ranges. Key electrical specifications include a typical power dissipation of 60mW at full speed, reducing to 8.5mW in shutdown mode. Performance metrics guarantee ±1LSB INL and DNL, with a Signal-to-Noise Plus Distortion ratio of 70dB and Total Harmonic Distortion of 74dB at Nyquist frequency.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ISW suffix indicates industrial temperature range operation (-40°C to +85°C). Confirm the TRPBF designation corresponds to tape and reel packaging containing 25 units per tube as specified in official documentation. Ensure compatibility with standard SO Wide 24-pin surface mount footprints during procurement planning.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a high-speed 12-bit resolution is required alongside low power consumption. The internal clock simplifies board layout by removing external oscillator requirements. Consider the ±1LSB linearity guarantees for precision measurement tasks. Evaluate the parallel interface requirements against available microprocessor bus capabilities before finalizing the design choice.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1279 family of sampling A/D converters. It shares architectural similarities with other SAR-based converters but distinguishes itself through integrated clocking and reference circuitry. The ISW variant specifically targets industrial applications requiring wider temperature stability compared to commercial grade counterparts within the same product lineage.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements are not explicitly confirmed in public datasheets. Verify functional equivalence regarding clock synchronization and reference voltage if substituting with other 12-bit, 600ksps ADCs. Check package dimensions and thermal characteristics to ensure mechanical fit.
