LTC1273BCN#PBF

Analog To Digital Converters (ADC) Overview

The LTC1273BCN#PBF is a 12-bit, 300ksps sampling analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It operates on a single 5V supply and accepts unipolar analog input voltages ranging from 0V to 5V. The device integrates a precision 2.42V reference with a maximum temperature coefficient of 25ppm/°C and an internally synchronized clock, eliminating the need for external timing components. Key performance metrics include a typical power dissipation of 75mW, a signal-to-noise plus distortion ratio of 70dB at Nyquist, and integral nonlinearity error within ±1/2LSB. It utilizes a high-speed parallel interface for data output.

Analog To Digital Converters (ADC) Procurement Notes

Verify that the component matches the specific BCN suffix configuration for commercial temperature range operation. Confirm the package type corresponds to the 24-lead narrow PDIP format as specified in the ordering information. Ensure compatibility with single 5V supply requirements for the LTC1273 variant.

Analog To Digital Converters (ADC) Selection Notes

Select this model for applications requiring unipolar 0V to 5V input ranges. The LTC1273 differs from the LTC1275 and LTC1276, which support bipolar inputs. Ensure the system design accommodates the 75mW typical power dissipation and provides adequate bypassing for the VDD and VREF pins to maintain specified linearity and noise performance.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC1273/LTC1275/LTC1276 family of 12-bit, 300ksps sampling A/D converters. While the LTC1275 and LTC1276 operate from dual supplies for bipolar inputs, the LTC1273 is specifically designed for single-supply unipolar applications. All variants share the same pinout and core architecture but differ in input voltage specifications.
