LTC1273BCSW#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1273BCSW#TRPBF is a 12-bit, 300ksps sampling analog-to-digital converter (ADC) from Analog Devices. It operates on a single 5V supply and accepts unipolar analog input signals ranging from 0V to 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 ±1/2LSB maximum integral nonlinearity (INL), ±3/4LSB maximum differential nonlinearity (DNL), 70dB signal-to-noise plus distortion ratio at Nyquist, and typical power dissipation of 75mW. It utilizes a high-speed parallel interface for microprocessor or DSP connectivity.

Analog To Digital Converters (ADC) Procurement Notes

Verify the #TRPBF suffix indicates lead-free tape and reel packaging. Confirm the BC grade corresponds to commercial temperature specifications (0°C to 70°C). Ensure the SW package matches the target PCB footprint requirements for the 24-lead SOIC wide form factor.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring a single-supply 5V architecture with unipolar inputs. The B-grade linearity specs suit general-purpose precision tasks. For bipolar input ranges, consider the LTC1275 or LTC1276 variants instead. Verify that the 600ns acquisition time meets the source impedance settling requirements of the driving amplifier.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1273/LTC1275/LTC1276 family of 12-bit, 300ksps sampling ADCs. The LTC1273 variant specifically supports unipolar 0V to 5V inputs on a single supply, whereas the LTC1275 and LTC1276 support bipolar inputs using dual supplies. All variants share the same core architecture, pinout, and performance characteristics regarding speed and noise.
