LTC1276BCSW#PBF

Analog To Digital Converters (ADC) Overview

The LTC1276BCSW#PBF is a 12-bit, 300ksps sampling analog-to-digital converter (ADC) from Analog Devices. It operates on single 5V or ±5V supplies with typical power dissipation of 75mW. The device features an internal 2.42V reference with 25ppm/°C drift and an internally synchronized clock, eliminating external clock requirements. It supports bipolar input ranges of ±5V via its high-impedance analog input. Key performance metrics include 70dB S/(N+D) and 77dB THD at the Nyquist frequency of 150kHz. Accuracy specifications for the B grade include ±1/2LSB maximum INL and ±3/4LSB maximum DNL.

Analog To Digital Converters (ADC) Procurement Notes

Verify the #PBF suffix indicates lead-free compliance and RoHS adherence per manufacturer standards. Confirm the BC SW designation corresponds to the commercial temperature range (0°C to 70°C) and the SOIC-24 wide package. Ensure sourcing channels provide valid traceability documentation for this specific Analog Devices part number.

Analog To Digital Converters (ADC) Selection Notes

Select the LTC1276 variant specifically for ±5V bipolar input applications; use LTC1273 for unipolar 0V-5V or LTC1275 for ±2.5V ranges. The B-grade specification offers tighter linearity limits compared to A-grade options. Consider the 75mW power dissipation and thermal characteristics when designing the PCB layout for the SOIC-24 package.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC1273/LTC1275/LTC1276 family of 12-bit, 300ksps ADCs. These devices utilize LTBiCMOS switched capacitor technology and share identical pinouts and control logic, differing primarily in input voltage ranges and internal reference configurations. The LTC1276 is optimized for bipolar signals requiring full ±5V swing.
