LTC1276ACSW#PBF

Analog To Digital Converters (ADC) Overview

The LTC1276ACSW#PBF is a 12-bit, 300ksps sampling analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It operates from dual ±5V supplies and accepts bipolar analog input signals within the range of ±5V. The device integrates a precision 2.42V reference with 25ppm/°C drift, an internal synchronized clock, and a 600ns sample-and-hold circuit. Key performance metrics include a typical power dissipation of 75mW, ±1/2LSB maximum integral nonlinearity (INL), and ±3/4LSB maximum differential nonlinearity (DNL). It features a high-impedance analog input and provides data via a parallel interface.

Ensure storage conditions adhere to humidity sensitivity levels specified in the datasheet prior to assembly.

Analog To Digital Converters (ADC) Selection Notes

Select this model for applications requiring bipolar ±5V input ranges. The LTC1273 variant supports unipolar 0V to 5V inputs, while the LTC1275 handles ±2.5V inputs. Ensure the system design accommodates the required ±5V dual supply rails and parallel bus timing constraints for reliable operation at 300ksps.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC127x family of 12-bit, 300ksps sampling ADCs. The family includes the LTC1273 (unipolar), LTC1275 (±2.5V bipolar), and LTC1276 (±5V bipolar). All variants share identical architecture, pinouts, and performance characteristics regarding speed, linearity, and power consumption, differing only in supported input voltage ranges.

Analog To Digital Converters (ADC) Replacement Considerations

Direct functional substitutes within the same package and specification profile are not explicitly listed in the provided documentation. Designers should evaluate other 12-bit SAR ADCs from Analog Devices or competitors, ensuring compatibility with parallel interfaces, ±5V supply requirements, and 300ksps throughput.
