LTC1275ACN#PBF

Analog To Digital Converters (ADC) Overview

The LTC1275ACN#PBF is a 12-bit, 300ksps sampling analog-to-digital converter (ADC) from Analog Devices. It operates on dual ±5V supplies and accepts bipolar analog input signals within the ±2.5V range. The device integrates a precision 2.42V reference with 25ppm/°C drift, an internal synchronized clock, and a 600ns sample-and-hold circuit. Key electrical specifications include ±1/2LSB maximum integral nonlinearity (INL), ±3/4LSB maximum differential nonlinearity (DNL), and a typical power dissipation of 75mW. It features a high-impedance analog input and a parallel digital interface for microprocessor connectivity.

Analog To Digital Converters (ADC) Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified suppliers. Confirm RoHS compliance status via official documentation. Ensure storage conditions adhere to specified humidity sensitivity levels to prevent package damage prior to soldering.

Analog To Digital Converters (ADC) Selection Notes

Select this model for applications requiring bipolar input handling with ±2.5V spans. The LTC1275 differs from the LTC1273 (unipolar 0-5V) and LTC1276 (bipolar ±5V). Ensure supply voltages meet minimum thresholds: VDD between +4.75V and +5.25V, and VSS between -2.45V and -5.25V for specified accuracy.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC127x family of 12-bit, 300ksps ADCs. It shares architectural similarities with the LTC1273 and LTC1276 but is specifically configured for bipolar operation. The 'ACN' suffix denotes the commercial temperature grade (0°C to 70°C) and the PDIP-24 package type.

Analog To Digital Converters (ADC) Replacement Considerations

Direct functional substitutes within the same family include the LTC1276ACN#PBF for wider voltage ranges or LTC1273ACN#PBF for unipolar applications. Verify pin compatibility and supply voltage requirements before substitution.
