LTC1276BCN#PBF

Analog To Digital Converters (ADC) Overview

The LTC1276BCN#PBF is a 12-bit, 300ksps sampling analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It operates from ±5V supplies and accepts bipolar analog input signals within the ±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 performance metrics include a typical Signal-to-Noise plus Distortion Ratio (S/(N+D)) of 70dB at Nyquist, ±1/2LSB maximum Integral Nonlinearity (INL), and ±3/4LSB maximum Differential Nonlinearity (DNL). It dissipates approximately 75mW and utilizes a high-speed parallel interface for data output.

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 remain within specified limits to maintain reliability. Check for lead-free marking consistency with the #PBF suffix designation.

Analog To Digital Converters (ADC) Selection Notes

Select the LTC1276BCN#PBF when bipolar ±5V input ranges are required with ±5V supplies. The 'B' grade offers standard commercial linearity specifications suitable for general-purpose applications. Consider the LTC1276ACN#PBF if tighter linearity tolerances are necessary. Ensure the system design accommodates the 24-pin PDIP package and parallel bus interface requirements.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC1273/LTC1275/LTC1276 family of 12-bit, 300ksps sampling ADCs. The LTC1276 variant specifically supports bipolar ±5V inputs, distinguishing it from the unipolar LTC1273 (0V to 5V) and the narrower bipolar LTC1275 (±2.5V). All variants share identical architecture, pinouts, and performance characteristics except for input voltage ranges.

Analog To Digital Converters (ADC) Replacement Considerations

Direct functional substitutes within the same family include the LTC1276ACN#PBF for improved linearity grades. Cross-family replacements require verification of interface compatibility and input range alignment.
