LTC1287CCN8#PBF

ADCs/DACs - Special Purpose Overview

The LTC1287CCN8#PBF is a single-chip 12-bit data acquisition system manufactured by Analog Devices Inc. It integrates a successive approximation A/D converter, analog multiplexer, and sample-and-hold circuit within an 8-lead plastic DIP package. The device operates on a single supply voltage ranging from 2.7V to 5V, with specifications guaranteed at 2.7V. It features a differential input configuration with an internal sample-and-hold on the positive terminal. The component utilizes a synchronous, half-duplex serial interface requiring only three wires for communication with microprocessors.

ADCs/DACs - Special Purpose Feature Summary

• 12-bit resolution with unipolar conversion capability
• Single supply operation (2.7V to 5V) with low power consumption of 1.0mA typical
• Built-in sample-and-hold on the (+) input channel
• Direct 3-wire serial interface compatible with MPU ports

ADCs/DACs - Special Purpose Applications

• Battery-powered instruments
• Data loggers
• Remote sensing applications

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix CN8 corresponds to the 8-lead plastic DIP package when sourcing. Confirm RoHS compliance status via official manufacturer documentation prior to integration. Ensure the operating environment remains within the specified commercial temperature range of 0°C to 70°C for guaranteed performance parameters.

ADCs/DACs - Special Purpose Selection Notes

Select this component for designs requiring a compact, low-voltage data acquisition solution with minimal external interface hardware. The 12-bit resolution and 30kHz maximum throughput are suitable for moderate-speed monitoring tasks. Ensure the analog source impedance is low enough to allow proper settling within the sample time constraints defined in the electrical characteristics.

ADCs/DACs - Special Purpose Part Context

This part belongs to the LTC1287 family of 3V data acquisition systems. The CCN8 designation indicates the commercial temperature grade variant housed in a standard plastic dual in-line package. It serves as a complete ADC solution, eliminating the need for separate sample-and-hold or reference buffer amplifiers in basic configurations.

ADCs/DACs - Special Purpose Replacement Considerations

Consult Analog Devices marketing for alternate sources if the N8 package is unavailable. Verify pin compatibility and electrical specifications before substituting with other 12-bit SAR ADCs, as serial interface protocols may differ.
