Overview
The LTC2619CGN#PBF is a quad 14-bit rail-to-rail voltage output digital-to-analog converter (DAC) in a 16-lead SSOP package. It features built-in high-performance output buffers and operates on a single supply voltage ranging from 2.7V to 5.5V. The device utilizes a 2-wire I²C compatible serial interface supporting standard mode (100kHz) and fast mode (400kHz). It incorporates a power-on reset circuit that holds outputs at zero-scale until a valid write and update occur. The DACs are guaranteed monotonic over temperature, with a maximum differential nonlinearity of ±1 LSB.
Feature Summary
- Quad 14-bit resolution with rail-to-rail voltage outputs
- I²C interface with 27 selectable addresses via CA0/CA1/CA2 pins
- Power-on reset to zero-scale for consistent initialization
- Individual channel power-down capability reducing current to 1µA max
Applications
- Mobile communications systems
- Process control and industrial automation
- Automatic test equipment and instrumentation
Procurement Notes
Verify the specific ordering suffix '#PBF' indicates lead-free finish and tube packaging as per Analog Devices documentation. Confirm the 'C' grade corresponds to the commercial temperature range of 0°C to 70°C. Ensure compatibility with the 16-lead narrow SSOP footprint during procurement planning.
Selection Notes
Select this component when four independent 14-bit channels are required in a compact form factor. The LTC2619 offers higher resolution than the LTC2629 but lower density than the LTC2609. Verify that the system requires separate reference inputs and I²C connectivity rather than SPI or parallel interfaces.
Part Context
This part belongs to the LTC2609/LTC2619/LTC2629 family of pin-compatible quad DACs. The LTC2619 specifically provides 14-bit resolution, positioned between the 16-bit LTC2609 and the 12-bit LTC2629. All variants share the same 16-lead SSOP package and I²C interface architecture.
Replacement Considerations
LTC2609CGN#PBF: Higher 16-bit resolution, pin-compatible. LTC2629CGN#PBF: Lower 12-bit resolution, pin-compatible. LTC2619IGN#PBF: Extended industrial temperature range (-40°C to 85°C), pin-compatible.
