LTC1290DCSW#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1290DCSW#TRPBF is a single-chip 12-bit data acquisition system manufactured by Analog Devices Inc. It integrates an 8-channel analog multiplexer, sample-and-hold circuit, and successive approximation A/D converter. The device supports unipolar or bipolar conversions 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 protocols, allowing direct connection to microprocessors via four-wire connections.

Analog To Digital Converters (ADC) Feature Summary

• Integrated 12-bit SAR ADC with 8-channel input multiplexer
• Software programmable for unipolar/bipolar modes and variable word lengths (8, 12, or 16 bits)
• Synchronous full-duplex serial interface supporting MSB-first or LSB-first data sequences
• Power shutdown capability for low-power applications

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring multi-channel signal conditioning
• Data logging equipment with moderate speed requirements
• Microprocessor-based measurement systems interfacing via SPI or Microwire

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging with lead-free compliance. Confirm the DC grade corresponds to the commercial temperature range of 0°C to 70°C. Ensure the SOIC-20 package dimensions match the target PCB footprint. Cross-reference the manufacturer part number with official Analog Devices documentation to confirm current production status.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a combined multiplexer and ADC solution is required to reduce board space. The 50kHz throughput limits suitability for high-speed audio or video applications. Verify that the source impedance of the analog inputs allows for proper settling within the sample time. Check if the available serial interface formats of the host processor align with the configurable MSB/LSB options.

Analog To Digital Converters (ADC) Part Context
