LTC1290BCSW#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1290BCSW#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 register (SAR) analog-to-digital converter. The device supports unipolar or bipolar conversion modes with a maximum throughput rate of 50kHz. It operates on a single +5V supply or dual ±5V supplies, drawing 6.0mA during active conversion. The component features a synchronous full-duplex serial interface compatible with industry-standard microprocessor ports.

Analog To Digital Converters (ADC) Feature Summary

• 12-bit resolution with 8 input channels configurable for single-ended or differential inputs
• On-chip sample-and-hold amplifier for all single-ended input channels
• Software programmable for MSB/LSB first data sequence and variable word lengths (8, 12, or 16 bits)
• Power shutdown capability via serial command to minimize consumption

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring multi-channel signal acquisition
• Data logging equipment for environmental monitoring
• Precision measurement instruments utilizing serial communication interfaces
• Embedded systems interfacing with microprocessors via SPI or Microwire protocols

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging and lead-free compliance. Confirm the BC grade corresponds to the commercial temperature range of 0°C to 70°C. Ensure the ordering quantity matches the reel specifications provided by the distributor. Cross-reference the manufacturer part number with official Analog Devices documentation to validate authenticity.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a high channel count is required in a single package. The internal sample-and-hold simplifies front-end design for single-ended inputs. Verify that the microprocessor interface supports the required serial clock frequencies up to 2MHz. Consider the power shutdown feature if battery operation or low standby current is a system requirement.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1290 family of general-purpose SAR ADCs. The 'BC' designation specifies the commercial temperature grade. The 'SW' indicates the 20-lead SOIC wide package. The '#TRPBF' suffix denotes tape and reel packaging with lead-free finish. Other variants include PDIP packages and industrial temperature grades.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements within the same series include LTC1290CCSW#TRPBF and LTC1290DCSW#TRPBF, which offer different temperature ranges or accuracy grades. For broader compatibility, check the LTC1293 or LTC1294 datasheets for similar functionality with varying channel counts or speeds.
