LTC1290BCN#PBF

Analog To Digital Converters (ADC) Overview

The LTC1290BCN#PBF is a single-chip 12-bit data acquisition system manufactured by Analog Devices. It integrates an 8-channel analog multiplexer, a high-speed sample-and-hold amplifier, and a successive approximation register (SAR) analog-to-digital converter with serial I/O. The device operates on a single +5V supply or dual ±5V supplies, achieving a maximum throughput rate of 50ksps. Key electrical specifications include a signal-to-noise ratio of 74dB, integral nonlinearity of 0.5LSB, and differential nonlinearity of 1LSB. It features software-programmable unipolar/bipolar conversion modes and accepts both differential and single-ended inputs.

Analog To Digital Converters (ADC) Feature Summary

• Integrated 8-channel multiplexer with software-selectable single-ended or differential input configurations
• Serial interface compatible with standard microprocessor ports, supporting MSB-first or MSB/LSB data sequencing
• Low power consumption of 30mW with a dedicated system shutdown mode for energy efficiency
• Built-in sample-and-hold circuitry enabling direct interfacing to most MPU parallel and serial ports

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring multi-channel signal acquisition
• Data logging equipment for environmental monitoring
• Battery-powered instrumentation utilizing single-supply operation
• Automotive test and measurement devices

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix #PBF indicates lead-free packaging compliant with RoHS directives. Confirm the BCN package variant corresponds to the 20-pin PDIP through-hole format. Check current availability status as distribution channels may list discontinuation or limited stock for legacy Linear Technology parts.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an 8-channel multiplexed input is required within a single IC footprint. Choose the LTC1290 over the LTC1296 if the system shutdown output pin is not needed. Ensure the 50ksps sampling rate meets application bandwidth requirements compared to the slower 46.5ksps variants in the family.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC129x family of single-chip 12-bit data acquisition systems. It shares architectural similarities with the LTC1293, LTC1294, and LTC1296, differing primarily in channel count, sampling speed, and specific pinout features like the shutdown output. The BCN designation identifies the commercial temperature range and PDIP package style.

Analog To Digital Converters (ADC) Replacement Considerations

The LTC1296BCN#PBF serves as a functional substitute within the same package, offering identical performance except for the inclusion of a system shutdown output pin. Verify pin compatibility before substitution.
