LTC2704CGW-12#TRPBF

Overview

The LTC2704CGW-12#TRPBF is a quad 12-bit voltage output SoftSpan DAC in a 44-lead SSOP package. It operates with analog supplies from ±4.5V to ±16.5V and digital logic from 2.7V to 5.5V. Key electrical parameters include ±1 LSB INL and DNL over the industrial temperature range (0°C to +70°C). The device features six programmable output spans, serial readback of on-chip registers via SPI, and outputs capable of driving ±5mA. Power consumption is low at 17.5mA typical supply current.

Feature Summary

• Quad 12-bit resolution with ±1 LSB INL/DNL accuracy
• Six programmable SoftSpan output ranges (unipolar/bipolar)
• Serial readback of all internal registers
• Outputs drive ±5mA load current

Applications

• Process control and industrial automation
• Direct digital waveform generation
• Software controlled gain adjustment
• Automated test equipment

Procurement Notes

Verify the #TRPBF suffix indicates tape and reel packaging for automated assembly. Confirm the CGW designation corresponds to the commercial temperature range of 0°C to +70°C. Ensure the specific lot date code meets project requirements as manufacturing schedules may vary.

Selection Notes

Select this part for applications requiring four independent 12-bit channels with wide bipolar output swings. Compare against LTC2704-14 or -16 if higher resolution is needed, noting that pinouts remain compatible across the family. Verify analog supply voltages support the desired output span configuration.

Part Context

This component belongs to the LTC2704 family of SoftSpan DACs. It shares pin compatibility with the 14-bit (LTC2704-14) and 16-bit (LTC2704-16) variants. The primary distinction is the 12-bit resolution and associated code word length for the CGW series.

Replacement Considerations

Pin-compatible substitutes within the same family include LTC2704CGW-14#TRPBF and LTC2704CGW-16#TRPBF. These offer higher resolutions but maintain identical footprints and software interfaces.
