LTC2704CGW-16#TRPBF

Overview

The LTC2704CGW-16#TRPBF is a quad, 16-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 an INL of ±2 LSB, DNL of ±1 LSB, and settling time of 4µs for a 5V step. The device features six programmable output ranges, serial readback via SPI, and outputs capable of driving ±5mA.

Feature Summary

• Quad 16-bit resolution with ±2 LSB INL and ±1 LSB DNL
• Six programmable SoftSpan output ranges: 0–5V, 0–10V, ±2.5V, ±5V, ±10V, –2.5V to 7.5V
• Serial readback of all on-chip registers via 3-wire SPI interface
• Force/Sense outputs enable remote sensing for improved load regulation

Applications

• Process control and industrial automation systems
• Direct digital waveform generation
• Automated test equipment requiring multi-channel precision

Procurement Notes

Verify the #TRPBF suffix indicates tape and reel packaging rather than tube. Confirm the CGW designation corresponds to the commercial temperature range (0°C to 70°C). Ensure the specific lot date code meets project requirements as manufacturing sources may vary.

Selection Notes

Select this part for applications requiring four independent 16-bit channels with software-selectable voltage spans. Compare against LTC2704IGW-16#TRPBF if operation below 0°C or above 70°C is required. Verify that the ±5mA output drive current suffices for the intended load impedance.

Part Context

This component belongs to the LTC2704 family, which includes 12-bit and 14-bit variants. The -16 suffix denotes 16-bit resolution. The CGW prefix specifies the plastic SSOP package and commercial temperature grade. The #TRPBF suffix identifies the tape and reel packaging format with lead-free finish.

Replacement Considerations

LTC2704IGW-16#TRPBF offers identical electrical performance but supports an extended industrial temperature range (-40°C to 85°C).
