Description for the DAC1282

The DAC1282 is a fully-integrated digital-to-analog converter (DAC) providing low distortion, digital synthesized voltage output suitable for testing of seismic equipment. The DAC1282 achieves very high performance in a small package with low power. Together, with the high-performance ADS1281 and ADS1282 analog-to-digital converters (ADCs), these devices create a measurement system that meets the exacting demands of seismic data acquisition equipment.

The DAC1282 integrates a digital signal generator, a DAC, and an output amplifier providing sine wave, dc, and pulse output voltages.

The output frequency is programmable from 0.5 Hz to 250 Hz and the magnitude is scaled by both analog and digital control. The analog gain is adjustable in 6-dB steps and the digital gain in 0.5-dB steps. The analog gain settings match those of the ADS1282 for testing at all gains with high resolution.

The DAC1282 also provides pulse outputs. The pulse amplitude is user-programmed and then selected by the pin for precise timing. Custom output signals can be generated by applying an external bitstream pattern.

A signal switch can be used to connect the DAC output to sensors for THD and impulse testing. The switch timing is controlled by pin and by command.

A SYNC pin synchronizes the DAC output to the analog-to-digital converter (ADC) sample interval. A power-down input disables the device, reducing power consumption to microwatts.

Carrier options

You can choose different carrier options based on the quantity of parts, including full reel, custom reel, cut tape, tube or tray.

A custom reel is a continuous length of cut tape from one reel to maintain lot- and date-code traceability, built to the exact quantity requested. Following industry standards, a brass shim connects an 18-inch leader and trailer on both sides of the cut tape for direct feeding into automated assembly machines. TI includes a reeling fee for custom reel orders.

Cut tape is a length of tape cut from a reel. TI may fulfill orders using multiple strips of cut tapes or boxes to satisfy the quantity requested.

TI often ships tube or tray devices inside a box or in the tube or tray, depending on inventory availability. We pack all tapes, tubes or sample boxes according to internal electrostatic discharge and moisture-sensitivity-level protection requirements.
