LTC1290DISW#PBF

Analog To Digital Converters (ADC) Overview

The LTC1290DISW#PBF is a monolithic 12-bit data acquisition system manufactured by Analog Devices (formerly Linear Technology). It integrates an 8-channel analog multiplexer, a high-speed successive approximation register (SAR) analog-to-digital converter (ADC), and a track-and-hold amplifier on a single chip. The device operates with a sampling rate of 50ksps and supports dual power supplies of ±5V or a single +5V supply. It features a serial interface compatible with standard microprocessors and is housed in a 20-lead SOIC package. The industrial temperature grade variant ensures reliable operation across a wide ambient range.

Analog To Digital Converters (ADC) Part Context

The LTC1290DISW#PBF belongs to the LTC1290 family of general-purpose SAR ADCs. The 'DI' suffix indicates an industrial temperature range (-40°C to +85°C), while 'SW' denotes the 20-lead SOIC package. The '#PBF' suffix signifies that the component is lead-free and RoHS compliant. This specific part number represents the tube packaging version of the industrial grade device, distinct from the tape-and-reel variants like the LTC1290DISW#TRPBF.

Analog To Digital Converters (ADC) Replacement Considerations

Publicly confirmed substitute part numbers include LTC1290BISW#TRPBF and LTC1290CISW#TRPBF. These equivalents share the same core architecture but may differ in speed grades or packaging formats. Verification of pin compatibility and electrical specifications against the original datasheet is required before substitution.
