LTC1276BCSW#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1276BCSW#TRPBF 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 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 electrical specifications include ±1/2LSB maximum integral nonlinearity (INL), ±3/4LSB maximum differential nonlinearity (DNL), and a typical power dissipation of 75mW. It utilizes a high-speed parallel digital interface for data output.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix #TRPBF indicates tape and reel packaging and lead-free compliance. Confirm the BC grade corresponds to commercial temperature operation (0°C to 70°C). Ensure the SW package variant matches the required surface mount footprint for the design.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a bipolar ±5V input range is required with a single ±5V supply configuration. The internal reference simplifies design by eliminating external voltage references. Verify that the 600ns acquisition time meets the source impedance settling requirements for the specific application bandwidth.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1273/LTC1275/LTC1276 family of 12-bit, 300ksps ADCs. The LTC1276 specifically supports ±5V bipolar inputs, whereas the LTC1273 supports 0V to 5V unipolar inputs and the LTC1275 supports ±2.5V bipolar inputs. All share identical architecture and pinouts.
