LTC1293BCN#PBF

Analog To Digital Converters (ADC) Overview

The LTC1293BCN#PBF is a single-chip 12-bit data acquisition system manufactured by Analog Devices Inc. It integrates a successive approximation A/D converter, an analog multiplexer, and a sample-and-hold circuit using LTCMOS switched capacitor technology. The device supports six input channels configured for single-ended or differential inputs. It operates on a single +5V supply or ±5V dual supplies, achieving a maximum throughput rate of 46.5ksps with a conversion time of 12µs max. The component features software-programmable unipolar/bipolar conversion modes and power shutdown capabilities.

Analog To Digital Converters (ADC) Procurement Notes

Verify the package type matches the required PCB footprint. The BCN suffix indicates a commercial temperature range (0°C to 70°C) and a 16-lead PDIP package. Confirm RoHS compliance status through official manufacturer documentation before finalizing procurement specifications.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 12-bit resolution and 46.5ksps sampling rate are sufficient for the application. Ensure the microprocessor interface supports the synchronous half-duplex serial protocol. For applications requiring more than six channels, consider the LTC1294 or LTC1296 variants within the same family.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1293/4/6 family of single-chip data acquisition systems. The LTC1293 specifically provides six input channels, whereas the LTC1294 and LTC1296 offer eight channels. The BCN designation specifies the commercial grade temperature range and plastic dual in-line package format.
