LTC1292DIN8#PBF

ADCs/DACs - Special Purpose Overview

The LTC1292DIN8#PBF is a single-chip 12-bit data acquisition system manufactured by Analog Devices Inc. It integrates a switched-capacitor successive approximation A/D converter, a differential input sample-and-hold on the positive terminal, and serial I/O within an 8-lead plastic DIP package. The device operates on a single 5V supply with a typical supply current of 6.0mA. It supports a maximum throughput rate of 60kHz and features a direct three-wire interface compatible with most microprocessor serial ports. Key electrical specifications include a resolution of 12 bits, a sampling rate of 60kS/s, and an SNR of approximately 74dB.

ADCs/DACs - Special Purpose Feature Summary

• 12-Bit SAR ADC with built-in sample-and-hold on the +IN input
• Single 5V supply operation with low power consumption (6.0mA typical)
• Direct 3-wire serial interface to MPU serial or parallel ports
• Analog inputs common mode range extends to supply rails

ADCs/DACs - Special Purpose Applications

• Remote data acquisition systems requiring minimal interconnects
• DSP applications utilizing high AC characteristics and 60kHz throughput
• Microprocessor-based monitoring where low power shutdown is beneficial

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix DIN8 corresponds to the 8-lead plastic DIP package. Confirm RoHS compliance status via the manufacturer's official documentation. Ensure the ordering part number matches the required temperature grade for the target application environment.

ADCs/DACs - Special Purpose Selection Notes

Select this component for applications requiring a single-channel differential input with 12-bit precision. Compare against the LTC1297 if automatic power shutdown between conversions is required, as the LTC1292 does not feature this function. Ensure the clock frequency and source resistance allow for adequate settling time within the sample period.

ADCs/DACs - Special Purpose Part Context

This part belongs to the LTC1292/LTC1297 family of 12-bit data acquisition systems. It shares functional similarities with the LTC1297 but lacks the power-down feature. It is distinct from higher-speed pipeline ADCs like the LTC2175 series and lower-resolution devices like the LTC1092.

ADCs/DACs - Special Purpose Replacement Considerations

The LTC1297CCN8#PBF is a related variant in the same family; however, it includes a power shutdown feature not present in the LTC1292. Direct pin-compatible substitutes are not explicitly listed in the provided datasheet text.
