LTC1292BIN8

ADCs/DACs - Special Purpose Overview

The LTC1292BIN8 is a single-channel, 12-bit Data Acquisition System (DAS) manufactured by Analog Devices Inc. under the Linear Technology brand. It integrates a high-speed successive approximation analog-to-digital converter (ADC), a precision voltage reference, and a low-drift sample-and-hold amplifier into a monolithic circuit. The device operates from a single +5V supply and features a serial data interface compatible with standard microprocessors. Designed for applications requiring moderate speed and resolution, it offers software-programmable features including unipolar/bipolar conversion modes and power shutdown capabilities.

• Integrated sample-and-hold amplifier and precision voltage reference
• Single +5V power supply operation
• Serial data interface with MSB-first or MSB/LSB output sequence options

ADCs/DACs - Special Purpose Applications

• Portable battery-powered instruments
• Industrial process control systems
• Data acquisition modules

ADCs/DACs - Special Purpose Part Context

The LTC1292BIN8 belongs to the LTC1292 family of single-chip data acquisition systems. The 'BIN8' suffix indicates an industrial temperature range variant (-40°C to +85°C) housed in an 8-pin CERDIP package. This component serves as a complete solution for converting analog signals to digital data without requiring external reference or hold amplifiers, simplifying board layout and reducing component count in embedded systems.

ADCs/DACs - Special Purpose Replacement Considerations

Direct replacements include other members of the LTC1292 family such as the LTC1292CCJ8 (commercial grade, 8-CDIP). When substituting, verify that the pinout compatibility matches the 8-pin DIP configuration and that the operating temperature range meets the system requirements. Ensure the replacement supports the required serial interface timing and voltage levels.
