DAC1282IPW

ADCs/DACs - Special Purpose Overview

The DAC1282IPW is a low distortion digital-to-analog converter manufactured by Texas Instruments, designed for seismic applications. It features a 24-bit resolution and supports a sampling rate of 256 kS/s with two channels. The device utilizes an SPI interface and provides voltage buffered outputs. It operates on analog supply voltages ranging from -2.6 V to 0 V and 4.75 V to 5.25 V, while the digital supply ranges from 1.65 V to 3.6 V. Key performance metrics include a settling time of 25 us, gain error of 0.75% FSR, and integral nonlinearity of +/- 16 LSB. Power consumption is specified at 38 mW.

ADCs/DACs - Special Purpose Feature Summary

• 24-bit resolution with 256 kS/s sampling rate
• Low distortion architecture optimized for seismic data acquisition
• Voltage buffered output with SPI serial interface
• Dual power supply support: Analog (-2.6V to 5.25V) and Digital (1.65V to 3.6V)

ADCs/DACs - Special Purpose Applications

• Seismic data acquisition systems
• High-resolution signal generation
• Precision instrumentation requiring low harmonic distortion

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'IPW' corresponds to the TSSOP-24 tube packaging variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets prior to procurement. Ensure voltage levels match the dual-supply requirements specified in the technical parameters.

ADCs/DACs - Special Purpose Selection Notes

Select this component for applications requiring high-resolution digital-to-analog conversion with minimal distortion. Compare against the ADS1282 series if simultaneous analog-to-digital conversion is needed. Verify that the 24-TSSOP package fits the PCB layout constraints and that the SPI interface timing meets system clock requirements.

ADCs/DACs - Special Purpose Part Context

The DAC1282IPW belongs to the DAC1282 family of low distortion digital-to-analog converters. It is often paired with ADCs like the ADS1282 in complete seismic data acquisition chains. The IPW suffix indicates a plastic small-outline package with wide body (TSSOP-24).

ADCs/DACs - Special Purpose Replacement Considerations

Check for the DAC1282IPWR variant for tape-and-reel packaging options. Evaluate the DAC1282AIPW for potential seismic-specific optimizations.
