LTC1415CSW#PBF

Analog To Digital Converters (ADC) Overview

The LTC1415CSW#PBF 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 true differential inputs supporting a 4.096V input range. The device integrates a precision reference, internal clock, and successive approximation architecture. Key performance metrics include –0.35LSB INL, –0.25LSB DNL, 72dB S/(N+D), and 80dB THD at 100kHz. It offers Nap and Sleep shutdown modes for low-power applications.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix #PBF indicates lead-free compliance and RoHS adherence per manufacturer standards. Confirm the 'CSW' designation corresponds to the commercial temperature range (0°C to 70°C) and SSOP-28 package. Ensure compatibility with 5V logic levels or configure OVDD for 3V operation if interfacing with lower voltage digital components.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a balance of speed and power is required for 12-bit conversion. The differential input structure is suitable for rejecting common-mode noise in noisy environments. Consider the internal reference for simplified designs, or use the VREF pin for external references if higher stability is needed. Ensure the driving source impedance is managed to meet the 150ns acquisition time requirement for full throughput.

Analog To Digital Converters (ADC) Part Context

The LTC1415 belongs to the LTC1415 series of high-speed, low-power ADCs. It is part of Analog Devices' portfolio of precision data converters designed for embedded applications requiring direct microprocessor or DSP interface via its parallel output port. The CSW variant specifically denotes the commercial grade version in the SSOP package.
