LTC1290CCSW#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1290CCSW#TRPBF is a single-chip 12-bit data acquisition system manufactured by Analog Devices Inc. It integrates an 8-channel analog multiplexer, a sample-and-hold circuit, and a successive approximation A/D converter. The device supports both unipolar and bipolar conversions with a maximum throughput rate of 50kHz. It operates on a single +5V supply or dual ±5V supplies, drawing 6.0mA. The component features a synchronous full-duplex serial interface compatible with industry standards, allowing direct connection to microprocessors. It is housed in a 20-lead SO Wide package.

Analog To Digital Converters (ADC) Feature Summary

• 12-bit resolution with 8 input channels configurable for single-ended or differential modes
• Built-in sample-and-hold circuit for all single-ended inputs
• Software programmable for unipolar/bipolar conversion, MSB/LSB-first output, and variable word lengths (8, 12, or 16 bits)
• Power shutdown capability via serial command for low power applications

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring multi-channel signal acquisition
• Data logging equipment with serial microprocessor interfaces
• Battery-powered instrumentation utilizing power shutdown features

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific temperature grade associated with the 'C' suffix against the required operating range. Confirm that the tape and reel packaging matches the automated assembly requirements. Ensure the lead-free designation corresponds to current environmental compliance standards for the target market.

Analog To Digital Converters (ADC) Selection Notes

Select this part when an 8-channel multiplexed input is required within a single IC. The 50kHz throughput suits moderate-speed applications. Verify that the microprocessor interface supports the required serial clock frequencies up to 2MHz. Consider the 20-SOIC package dimensions for PCB layout constraints.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC1290 family of single-chip data acquisition systems. The 'CCSW' designation indicates the commercial temperature range (0°C to 70°C) and the 20-lead plastic SO Wide package. Other variants include industrial temperature ranges and different package types such as PDIP or CERDIP.
