Overview
The LTC2619IGN#PBF is a quad 14-bit rail-to-rail voltage output digital-to-analog converter (DAC) in a 16-lead SSOP package. It operates on a single supply voltage ranging from 2.7V to 5.5V and features built-in high-performance output buffers guaranteed monotonic over temperature. The device utilizes a 2-wire I²C compatible serial interface supporting standard mode (100kHz) and fast mode (400kHz). Key specifications include a settling time of 9µs, differential nonlinearity of ±1 LSB, and integral nonlinearity of ±4 LSB. Supply current is 1mA at 3V, with individual channel power-down capability reducing current to 1µA maximum.
Feature Summary
- Quad 14-bit resolution with rail-to-rail voltage outputs and built-in buffers
- I²C interface with 27 selectable addresses and global address support
- Power-on reset to zero-scale for consistent system initialization
- Ultralow crosstalk between DACs (<5µV) and high drive capability (±15mA min)
Applications
- Mobile Communications
- Process Control and Industrial Automation
- Automatic Test Equipment and Instrumentation
Procurement Notes
Verify the specific suffix IGN indicates the industrial temperature range (-40°C to +85°C) and SSOP-16 package. Confirm #PBF denotes lead-free finish. Check datasheet for availability of tape and reel options if automated assembly is required.
Selection Notes
Select this component when four independent 14-bit channels are needed in a compact footprint. Compare against LTC2609 for higher 16-bit resolution or LTC2629 for lower cost 12-bit performance. Ensure I²C bus speed requirements align with the 400kHz fast mode specification.
Part Context
This part belongs to the LTC2609/LTC2619/LTC2629 family of pin-compatible quad DACs. The 'LTC2619' designation specifically identifies the 14-bit resolution variant within this series, sharing the same package and interface as the 16-bit and 12-bit versions.
Replacement Considerations
LTC2609IGN#PBF offers 16-bit resolution with identical pinout. LTC2629IGN#PBF provides 12-bit resolution with identical pinout. For SPI interface alternatives, consider the LTC26xx series.
