Overview
The LTC2704IGW-14#PBF is a quad, 14-bit voltage output SoftSpan digital-to-analog converter (DAC) in a 44-lead SSOP package. It operates from 3V to 5V logic and ±5V to ±15V analog supplies. Key specifications include ±1 LSB INL and DNL over the industrial temperature range (-40°C to +85°C). The device features six programmable output ranges, serial readback of all on-chip registers, and outputs that drive ±5mA. Power consumption is low, with supply current typically at 17.5mA for analog supplies and 2µA for digital logic.
Feature Summary
- Quad 14-bit DACs with ±1 LSB INL/DNL accuracy
- Six programmable output spans: 0V–5V, 0V–10V, ±2.5V, ±5V, ±10V, –2.5V to 7.5V
- Serial readback of code and span registers via SRO pin
- Outputs drive ±5mA load current with glitch impulse < 2nV-sec
Applications
- Process control and industrial automation
- Direct digital waveform generation
- Software controlled gain adjustment
- Automated test equipment
Procurement Notes
Verify component authenticity through authorized Analog Devices distributors or direct channels. Confirm the specific -14 suffix indicates 14-bit resolution and check for lead-free compliance markings. Ensure storage conditions adhere to moisture sensitivity levels prior to soldering.
Selection Notes
Select this part when four independent 14-bit channels with wide bipolar/unipolar voltage ranges are required. Compare against LTC2704-16 for higher resolution or LTC2704-12 for cost optimization if 12-bit precision suffices. Ensure analog supply rails support the desired output swing and load current requirements.
Part Context
This component belongs to the LTC2704 family of SoftSpan DACs. It shares pin compatibility with the 12-bit (LTC2704-12) and 16-bit (LTC2704-16) variants, allowing for design flexibility across different resolution needs within the same footprint.
Replacement Considerations
Pin-compatible alternatives within the same series include LTC2704IGW-16#PBF (16-bit) and LTC2704IGW-12#PBF (12-bit). Verify that the replacement matches the required resolution and electrical characteristics for the specific application.
