LTC1415CSW#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1415CSW#TRPBF is a 12-bit, 1.25Msps sampling analog-to-digital converter (ADC) from Analog Devices Inc., housed in a 28-lead plastic SSOP package. It operates on a single 5V supply with a power dissipation of 55mW and features internal reference and clock circuitry. The device provides true differential inputs with a full-scale range of 4.096V, achieving –0.35LSB INL and –0.25LSB DNL. Key performance metrics include 72dB S/(N+D) and 80dB THD at 100kHz input frequency.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix #TRPBF indicates tape and reel packaging when sourcing components. Confirm that the 'C' grade designation corresponds to the commercial temperature range of 0°C to 70°C as specified in the datasheet. Ensure compatibility with standard SSOP-28 footprints during procurement planning.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring a balance of speed and power efficiency under a single 5V supply. The internal reference simplifies design by eliminating external voltage references. Consider the 150ns acquisition time when driving high source impedance signals, potentially requiring an input buffer amplifier to maintain throughput rates.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1415 family of 12-bit sampling ADCs. The CSW variant specifically denotes the commercial temperature range and SSOP-28 plastic package. It serves as a parallel-output successor to earlier SAR architectures, offering direct microprocessor interfacing without pipeline delay.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements within the same family include the LTC1415CG#TRPBF (SSOP-28, commercial grade) and LTC1415ISW#TRPBF (SOIC-28, industrial grade). Verify package dimensions and thermal characteristics when substituting between SSOP and SOIC variants.
