DAC1282AIPWR

ADCs/DACs - Special Purpose Overview

The DAC1282AIPWR is a low distortion digital-to-analog converter manufactured by Texas Instruments, designed for seismic applications. It features a 24-bit resolution with a sampling rate of 256 kS/s and supports two channels. The device utilizes an SPI interface and provides voltage buffered outputs. Power requirements include analog supply voltages ranging from -2.6 V to 0 V and 4.75 V to 5.25 V, alongside a digital supply voltage of 1.65 V to 3.6 V. Key performance metrics include a settling time of 25 µs, gain error of 0.75% FSR, and INL of +/- 16 LSB. It operates within a temperature range of -40°C to +85°C and is housed in a TSSOP-24 package.

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'PW' versus 'PWR' when sourcing, as packaging differs (tube vs. tape and reel). Confirm RoHS compliance status through official manufacturer documentation. Check humidity sensitivity level (MSL 2) for storage and handling requirements during assembly. Ensure voltage supply rails match the specified ranges for both analog and digital domains.

ADCs/DACs - Special Purpose Selection Notes

Select this component for applications requiring high resolution and low distortion in seismic monitoring. Compare against the IPW variant if tube packaging is preferred over tape and reel. Verify that the 256 kS/s sampling rate meets system bandwidth needs. Ensure the TSSOP-24 footprint fits the PCB layout constraints.

ADCs/DACs - Special Purpose Part Context

This part belongs to the DAC1282 series from Texas Instruments, which focuses on high-performance data converters. The DAC1282AIPWR is the tape-and-reel version of the DAC1282AIPW. It shares core specifications with other members of the family but differs in packaging and potentially temperature grades depending on the specific suffix.
