Overview
The LTC2619IGN#TRPBF 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 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 (100kHz) and fast (400kHz) modes. Each channel includes individual power-down capability, reducing current consumption to 1µA maximum per channel. Power-on reset circuits ensure outputs remain at zero-scale during initialization.
Feature Summary
- Quad 14-bit resolution with rail-to-rail voltage outputs
- I²C interface with 27 selectable addresses via CA0/CA1/CA2 pins
- Individual channel power-down mode (max 1µA per DAC)
- Guaranteed monotonic operation over the full operating temperature range
Applications
- Mobile communications systems
- Process control and industrial automation
- Automatic test equipment and instrumentation
Procurement Notes
Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm the IGN designation corresponds to the industrial temperature grade of –40°C to +85°C. Ensure the I²C bus pull-up resistors are selected appropriately for the system voltage and capacitance requirements to maintain signal integrity at 400kHz.
Selection Notes
Select this component for applications requiring four independent analog outputs in a compact footprint. The 14-bit resolution offers a balance between precision and data throughput. Consider the LTC2619-1 variant if mid-scale power-on reset behavior is required instead of the zero-scale default found in the standard LTC2619.
Part Context
This part belongs to the LTC2609/LTC2619/LTC2629 family of pin-compatible quad DACs. The primary distinction within the family is resolution: the LTC2609 provides 16 bits, the LTC2619 provides 14 bits, and the LTC2629 provides 12 bits. All variants share the same 16-lead SSOP package and electrical interface characteristics.
Replacement Considerations
The LTC2619CGN#TRPBF serves as a commercial grade alternative with an operating range of 0°C to 70°C. For higher resolution needs, the LTC2609IGN#TRPBF (16-bit) is available. For lower resolution requirements, the LTC2629IGN#TRPBF (12-bit) is compatible.
