Overview
The LTC2704IGW-16#TRPBF is a quad, 16-bit voltage output DAC in a 44-lead SSOP package. It features SoftSpan technology with six programmable ranges: unipolar 0V to 5V/10V and bipolar ±2.5V/±5V/±10V/–2.5V to 7.5V. Operating from ±5V to ±15V analog supplies and 3V to 5V logic, it delivers 1LSB INL/DNL accuracy over the industrial temperature range (–40°C to 85°C). The device supports serial readback of all registers via a 3-wire SPI interface, includes force/sense outputs for remote sensing, and provides glitch impulse performance under 2nV-sec.
Feature Summary
- Quad 16-bit resolution with 1LSB INL and DNL accuracy across the full industrial temperature range.
- SoftSpan architecture enabling six software-programmable output voltage spans.
- Serial readback capability allows verification of any on-chip register within one instruction cycle.
- Force/Sense outputs facilitate remote sensing to compensate for trace resistance.
Applications
- Process control and industrial automation systems
- Direct digital waveform generation
- Software controlled gain adjustment circuits
- Automated test equipment
Procurement Notes
Verify that the #TRPBF suffix indicates tape and reel packaging rather than tube packaging. Confirm the 'I' grade designation matches the required –40°C to 85°C operating temperature range for the specific application environment.
Selection Notes
Select this part when four independent 16-bit channels are required with high linearity. Ensure the system requires the specific SoftSpan voltage ranges provided. Verify that the 44-lead SSOP footprint fits the PCB layout constraints compared to alternative packages.
Part Context
This component belongs to the LTC2704 family, which includes 12-bit and 14-bit variants. All versions share identical pinouts and functionality, differing only in resolution and specific INL specifications. The IGW-16 variant specifically targets applications requiring maximum precision among the series.
Replacement Considerations
Pin-compatible alternatives include the LTC2704IGW-14#TRPBF and LTC2704IGW-12#TRPBF. These parts offer lower resolutions but maintain the same package and interface compatibility.
